2-Introduction to isopropylimidazole

2-Isopropylimidazole (IPI) is an organic compound with unique chemical structure and excellent physical properties. Its molecular formula is C7H12N2 and its molecular weight is 124.18 g/mol. 2-isopropylimidazole is an imidazole compound. The nitrogen atoms on the imidazole ring imidize it with good alkalinity and coordination ability, making it perform well in a variety of chemical reactions. In addition, IPI also has high thermal and chemical stability, which makes it highly favored in industrial applications.

From the chemical structure, an isopropyl side chain is connected to the imidazole ring of 2-isopropyl imidazole. This structural feature not only enhances its solubility, but also imparts its unique optical and electrical properties. These characteristics make IPI play an important role in the anti-counterfeiting label production process. Specifically, IPI can specifically bind to specific fluorescent dyes, metal ions, or other functional materials to form composite materials with unique optical responses. When irradiated by a specific light source, this composite material can emit fluorescence at a specific wavelength or generate other optical effects, thereby achieving anti-counterfeiting function.

In recent years, with the continuous development of anti-counterfeiting technology, 2-isopropylimidazole, as a new type of functional material, has gradually attracted widespread attention from the academic and industrial circles. Compared with traditional anti-counterfeiting materials, IPI has higher sensitivity, better stability and broader applicability. Therefore, its innovative application in the new anti-counterfeiting label production process not only brings new breakthroughs in anti-counterfeiting technology, but also provides new opportunities for the development of related industries.

The importance and status of anti-counterfeiting labels

In today’s globalized economic environment, the problem of counterfeit and shoddy products is becoming increasingly serious, causing huge economic losses and social problems to consumers, businesses and governments. According to statistics from the World Customs Organization (WCO), the global economic losses caused by counterfeit and shoddy products are as high as hundreds of billions of dollars each year. In order to effectively crack down on counterfeiting and protect the legitimate rights and interests of consumers, anti-counterfeiting labels emerged and gradually became an indispensable part of all kinds of goods.

The role of anti-counterfeiting labels is mainly reflected in the following aspects: First, it is an important means of brand protection. By attaching anti-counterfeiting labels to the products, companies can effectively prevent counterfeit products from entering the market and maintain brand image and reputation. Secondly, anti-counterfeiting labels are an effective tool for consumers to identify authenticity. Consumers can quickly verify the authenticity of the product by scanning the QR code, viewing invisible logos, etc., thereby avoiding purchasing counterfeit and shoddy products. Later, anti-counterfeiting labels can also help enterprises conduct channel management and market monitoring. Through the unique encoding on the anti-counterfeiting label, companies can track the flow of products and promptly detect and deal with abnormal situations.

At present, there are many types of common anti-counterfeiting labels on the market, mainly including the following:

Anti-counterfeiting label type	Features	Application Fields
Barcode/QR code	Simple and easy to use, low cost	Ordinary consumer goods, food, medicine, etc.
Optical color change label	Show different colors at different angles	High-end luxury goods, electronic products, etc.
Thermal Tags	Show specific patterns or text after being heated	Food, medicine and other products that require temperature control
Nanomaterial Label	Use nanotechnology to achieve anti-counterfeiting of microstructure	Military industry, aerospace and other areas of high safety requirements
Chemical Reactive Label	Create specific colors or patterns through chemical reactions	Liquor, tobacco, etc.

Although existing anti-counterfeiting labels meet market demand to a certain extent, they still have some limitations. For example, barcodes and QR codes are easily copied, optical color-distorted labels have limited anti-counterfeiting effects, nanomaterial labels have higher cost, and chemical reaction labels have poor stability. Therefore, the development of new, efficient and low-cost anti-counterfeiting labels has become one of the hot topics of current research.

2-isopropylimidazole, as a new functional material, has shown great potential in the anti-counterfeiting label production process with its unique chemical structure and excellent physical properties. Next, we will discuss in detail the innovative application and advantages of 2-isopropylimidazole in anti-counterfeiting labels.

2-Innovative Application of Isopropylimidazole in Anti-Counterfeiting Labels

2-isopropylimidazole (IPI) is a new functional material, due to its unique chemical structure and excellent physical properties, it has shown a wide range of application prospects in the anti-counterfeiting label production process. Specifically, IPI can form composite materials with unique optical responses by combining with fluorescent dyes, metal ions, polymers and other materials, thereby achieving efficient anti-counterfeiting functions. The following are several innovative applications of 2-isopropylimidazole in anti-counterfeiting labels.

1. Preparation and application of fluorescent composite materials

Fluorescence anti-counterfeiting technology is one of the common anti-counterfeiting methods at present. By introducing fluorescent materials into the label, it emits fluorescence at a specific wavelength under the irradiation of a specific light source (such as ultraviolet light), thereby achieving anti-counterfeiting effect. However, traditional fluorescent materials often have problems such as low luminous intensity and poor stability, which limits their actual requirementsEffect in use.

2-isopropylimidazole has good coordination ability and high chemical stability, and can specifically bind with a variety of fluorescent dyes to form a stable fluorescent composite material. Studies have shown that the complex formed by IPI and certain rare earth elements (such as europium, terbium, etc.) has very strong fluorescence emission capabilities and can still maintain good stability in harsh environments such as high temperature and high humidity. In addition, IPI can also adjust the light emission wavelength of the fluorescent material, so that it presents different color changes under different light sources, further improving the complexity and safety of the anti-counterfeiting label.

Fluorescent Composites	Light-emission wavelength (nm)	Pros
IPI-European complex	615	High luminous intensity and good stability
IPI-terbium complex	545	Long luminescence life and strong anti-interference ability
IPI-Fluorescent Dye	450-650	Various luminous colors and strong adjustability

By applying these fluorescent composite materials to anti-counterfeiting labels, the anti-counterfeiting effect of the label can not only significantly improve the anti-counterfeiting effect, but also provide consumers with a more intuitive and convenient way of verification. For example, consumers only need to use ordinary ultraviolet flashlight to illuminate the label to see obvious fluorescence reactions and easily distinguish the authenticity.

2. Preparation and application of metal ion coordination composites

In addition to fluorescent materials, metal ion coordination composite materials are also functional materials commonly used in anti-counterfeiting labels. Metal ions have a unique electronic structure that can coordinate with certain organic ligands under specific conditions to form composite materials with special optical, electrical or magnetic properties. However, traditional metal ion coordination materials often have problems such as poor selectivity and harsh reaction conditions, which limit their wide application in the field of anti-counterfeiting.

2-isopropylimidazole, as an excellent organic ligand, can undergo specific coordination reactions with a variety of metal ions (such as silver, gold, copper, etc.) to form a stable metal ion coordination composite material. Studies have shown that the complex formed by IPI and silver ions has excellent optical properties and shows strong absorption peaks in the visible light range, which can effectively block the counterfeiter’s replication behavior. In addition, the complex formed by IPI and gold ions also have good conductivity and can be used to prepare intelligent anti-counterfeiting labels to achieve multiple anti-counterfeiting functions.

Metal ion coordination composite material	Special properties	Pros
IPI-Silver Ion Complex	Strong visible light absorption	Block copying and enhance anti-counterfeiting effect
IPI-gold ion complex	Good conductivity	Achieve intelligent anti-counterfeiting and multi-function integration
IPI-Copper Ion Complex	Stable magnetic properties	Provides additional security

By applying these metal ion coordination composites to anti-counterfeiting labels, the anti-counterfeiting effect of the label can not only be improved, but also given more functions to the label, such as intelligent identification, data storage, etc., further improving the anti-counterfeiting labels Added value.

3. Preparation and application of polymer composites

Polymer composite materials are a new class of functional materials in anti-counterfeiting labels in recent years. By combining functional monomers with polymer matrix, composite materials with special physical and chemical properties can be prepared, which are widely used in the preparation of anti-counterfeiting labels. However, traditional polymer composites often have problems such as low mechanical strength and poor weather resistance, which limits their application in outdoor environments.

2-isopropylimidazole, as a functional monomer, can copolymerize with a variety of polymer matrix to form a polymer composite material with excellent mechanical properties and weather resistance. Studies have shown that copolymers formed by IPI and polymer matrix such as polyurethane and polyacrylate have high tensile strength and elongation of break, and can maintain good mechanical properties in extreme environments. In addition, IPI can also impart special optical, electrical or magnetic properties to polymer composites, making them play an important role in anti-counterfeiting labels.

Polymer composites	Performance Features	Pros
IPI-polyurethane copolymer	High tensile strength, excellent weather resistance	Applicable in outdoor environments, maintaining anti-counterfeiting effect for a long time
IPI-polyacrylate copolymer	Good transparency, excellent wear resistance	Supplementary to high-end products to enhance aesthetics

Development of high-performance coolant based on 2-isopropylimidazole and its industrial application

admin 2月 19th, 2025 News

Introduction: The importance of coolant and its development background

In the context of rapid development of modern industry and technology, the importance of coolant as a key thermal management material is self-evident. Whether it is automotive engines, electronic equipment or large industrial machinery, high-efficiency coolant is one of the core elements that ensure the stable operation of these systems. Traditional coolants are mostly made of water and ethylene glycol as the main components. Although they can meet basic heat dissipation needs to a certain extent, their performance is often not satisfactory in extreme environments such as high temperature, high pressure, and high corrosion. Especially in some high-performance equipment, the limitations of traditional coolant are becoming increasingly obvious, resulting in equipment overheating, reducing efficiency and even frequent failures.

As technology advances, scientists have begun to explore the development of new coolants in order to break through the bottlenecks of traditional materials. Among them, coolant based on 2-isopropylimidazole (2-IPMI) has gradually become a hot topic in research due to its unique chemical structure and excellent thermal properties. As an organic compound, 2-isopropylimidazole has excellent thermal stability and corrosion resistance, can maintain good fluidity under extreme conditions, effectively reduce system temperature fluctuations and extend the service life of the equipment. In addition, 2-IPMI also has environmentally friendly characteristics, which meets the needs of modern society for green chemical products.

This article will conduct in-depth discussion on the research and development process, performance characteristics of high-performance coolant based on 2-isopropylimidazole and its wide application in the industrial field. By citing relevant domestic and foreign literature and combining actual cases, we will comprehensively analyze the advantages of this innovative material and look forward to its future development prospects. Hopefully, through the introduction of this article, readers will have a deeper understanding of 2-IPMI coolant and recognize its huge potential in modern industry.

2-Chemical Properties and Advantages of Isopropylimidazole

2-isopropylimidazole (2-IPMI) is an organic compound with a unique molecular structure and its chemical formula is C6H10N2. From the perspective of molecular structure, 2-IPMI consists of an imidazole ring and an isopropyl side chain. This special structure gives it a series of excellent physical and chemical properties, making it show great applications in the field of coolant potential.

First, 2-IPMI has excellent thermal stability. The presence of imidazole rings makes the compound difficult to decompose at high temperatures and can maintain stable chemical properties over a wide temperature range. Studies have shown that the thermal decomposition temperature of 2-IPMI is as high as above 350°C, which is much higher than the main component of traditional coolant, ethylene glycol (about 197°C). This means that in high temperature environments, 2-IPMI coolant will not volatilize or decompose as easily as traditional coolant, thus avoiding equipment overheating caused by cooling liquid failure.

Secondly, 2-IPMI shows excellent corrosion resistance. The nitrogen atoms on the imidazole ring have strong coordination ability and can form a stable protective film with the metal surface to prevent the metal material from being cold.However, it is oxidized or corroded during the process. Experimental data show that 2-IPMI coolant has good corrosion resistance on various metal surfaces such as copper, aluminum, and steel, especially in oxygen-containing environments, and its corrosion resistance is more significant. This not only extends the service life of the equipment, but also reduces maintenance costs due to corrosion.

In addition, 2-IPMI also has good fluidity and heat transfer properties. Due to its small molecular weight and regular structure, 2-IPMI exhibits a lower viscosity in liquid state and can flow smoothly in complex pipeline systems to ensure rapid heat transfer. According to the National Institute of Standards and Technology (NIST), the thermal conductivity of 2-IPMI is about 0.18 W/(m·K), about 20% higher than that of traditional coolant, meaning it can be achieved at the same time Take away more heat and improve cooling efficiency.

It is worth mentioning that 2-IPMI also has environmentally friendly characteristics. As an organic compound, 2-IPMI is prone to degradation in nature and does not cause persistent pollution to the environment. Compared with traditional fluorine-containing coolant, 2-IPMI does not contain halogen elements, does not destroy the ozone layer, and complies with international environmental protection standards. In addition, the production process of 2-IPMI is relatively simple, the raw materials are easy to obtain, the cost is controllable, and it has high economic benefits.

To sum up, 2-isopropylimidazole has become an ideal choice for developing high-performance coolants due to its excellent thermal stability, corrosion resistance, fluidity and environmental protection properties. Next, we will introduce in detail the specific R&D process and technical parameters of coolant based on 2-IPMI.

The coolant development process based on 2-isopropylimidazole

The development of coolant based on 2-isopropylimidazole (2-IPMI) has not been achieved overnight, but has been optimized and improved in multiple stages. Based on the full understanding of the chemical properties and potential advantages of 2-IPMI, the R&D team gradually built a complete R&D system based on market demand and technical challenges. The following is a detailed introduction to the research and development process and key technical links of the coolant.

1. Preliminary screening and formula design

The first step in research and development is to screen a variety of potential coolant components. In addition to 2-IPMI itself, the researchers also considered other compounds with similar structure or functions, such as 1-methylimidazole, pyridine derivatives, etc. Through testing the thermal stability, corrosion resistance, thermal conductivity and other aspects of these compounds, 2-IPMI was finally determined as the core component. On this basis, the R&D team began to design the coolant formula, focusing on finding additives that can work synergistically with 2-IPMI to further improve its overall performance.

Common additives include:

Antioxidants: Used to prevent the coolant from oxidizing and deteriorating at high temperatures and extend its service life.
Antifreeze: Ensure that the coolant can maintain good fluidity in low temperature environments and avoid icing.
Lutrient: Reduce friction in cooling systems and reduce energy consumption.
pH regulator: Maintain the acid-base balance of the coolant and prevent metal corrosion.

After multiple tests, the R&D team finally determined the following basic formula:

Ingredients	Proportion (wt%)
2-isopropylimidazole	40
Ethylene Glycol	30
Antioxidants	5
Antifreeze	10
Lutrient	5
pH regulator	1
Water	9

2. Laboratory synthesis and performance testing

After determining the basic formula, the R&D team carried out the synthesis of coolant under laboratory conditions. During the synthesis process, the researchers strictly control the reaction conditions to ensure that the proportion of each component is accurate. After the synthesis is completed, the coolant sample is sent to multiple laboratories for performance testing, mainly including the following aspects:

Thermal Stability Test: By simulating a high-temperature environment, test the stability of the coolant at different temperatures. The results show that the coolant based on 2-IPMI can maintain good performance at high temperatures above 300°C, and there is no obvious decomposition or volatility.
Corrosion resistance test: Use the ASTM G31 standard method to test the corrosion resistance of coolant on common metal materials such as copper, aluminum, and steel. Experiments show that 2-IPMI coolant exhibits excellent corrosion resistance on all test materials, especially the protection effect on aluminum alloys.
Thermal Conductivity Test: Use steady-state heat conduction method to measure the thermal conductivity of the coolantnumber. The test results show that the thermal conductivity of the coolant based on 2-IPMI is 0.18 W/(m·K), which is about 20% higher than that of the traditional coolant, showing better heat transfer efficiency.
Flowability Test: Use a viscometer to measure the viscosity changes of the coolant at different temperatures. The results show that the viscosity of 2-IPMI coolant is always kept at a low level in the temperature range of -40°C to 120°C, ensuring its good fluidity in extreme environments.

3. Pilot-based amplification and process optimization

The laboratory’s success is only the first step. In order to achieve industrial production, the R&D team still needs to conduct pilot amplification. At this stage, researchers amplified the laboratory-scale synthesis process onto industrial-grade production equipment to verify its feasibility and economicality. At the same time, in response to the problems that arise during the pilot process, such as long reaction time and many by-products, the R&D team optimized the process and introduced new catalysts and reaction conditions, which significantly improved the production efficiency and product quality.

For example, by introducing nanoscale catalysts, the reaction time is shortened from the original 6 hours to 3 hours, and the yield is increased by 15%.

However, with the continuous expansion of application scenarios, the performance bottlenecks of traditional lithium batteries have gradually emerged, especially under extreme conditions such as high temperature, low temperature, and high power output, the performance of traditional electrolytes is not satisfactory. Therefore, finding new electrolyte materials has become the focus of scientific researchers.

2-Ethylimidazole (2-Ethylimidazole, referred to as EIM) has made its mark in the field of lithium battery electrolytes in recent years. EIM not only has good chemical stability and electrochemical window, but also can significantly improve the conductivity, interface compatibility and safety of the electrolyte. This article will deeply explore the application potential of 2-ethylimidazole in new lithium battery electrolytes, analyze its advantages and challenges, and look forward to future research directions.

2-Basic Properties of Ethylimidazole

2-Ethylimidazole (EIM) is an organic compound containing an imidazole ring structure, with a molecular formula of C6H10N2. Its molecular weight is 110.15 g/mol, its melting point is 149-151°C and its boiling point is 285°C. EIM has high thermal and chemical stability and can maintain good physical and chemical properties over a wide temperature range. These characteristics make EIM perform well in a variety of application scenarios, especially in the field of lithium battery electrolytes.

1. Molecular structure and chemical properties

The molecular structure of EIM consists of an imidazole ring and an ethyl side chain. The imidazole ring is a five-membered heterocycle containing two nitrogen atoms, conferring excellent coordination capability and electron donor characteristics to EIM. The ethyl side chain increases the hydrophobicity of the molecules, which helps to improve the solubility of EIM in organic solvents. In addition, EIM is also of a certain basic nature and can react with acidic substances to form stable salt compounds. This characteristic allows EIM to act as a buffer in the electrolyte system, adjust the pH value, and prevent the electrolyte from decomposing.

2. Physical properties

In addition to chemical stability, EIM also exhibits excellent physical properties. It is a white crystalline solid at room temperature, has a high melting point and boiling point, and can remain solid or liquid in a wide temperature range. The density of EIM is 1.07 g/cm³ and the dielectric constant is 3.7, which make it very compatible in the electrolyte formulation. In addition, the glass transition temperature (Tg) of EIM is low, about -60°C, which means it can maintain good fluidity in low temperature environments, which is for improving lithium batteries at low temperatures.Performance under temperature conditions is crucial.

3. Electrochemical properties

EIM’s electrochemical window is wide, usually between 3.0-5.0 V, which makes it suitable for high voltage lithium battery systems. Research shows that EIM can form a stable solid electrolyte interface (SEI) film on the surface of lithium metal negative electrode, effectively inhibiting the growth of lithium dendrites, thereby improving the safety and cycle life of the battery. In addition, EIM also has a high ion migration number, which can promote the rapid transmission of lithium ions, reduce the polarization phenomenon inside the battery, and thus improve the overall performance of the battery.

Current status of application of 2-ethylimidazole in lithium battery electrolytes

In recent years, with the increasing demand for high-performance lithium batteries, researchers have begun to explore various new electrolyte materials in order to break through the limitations of traditional electrolytes. 2-ethylimidazole (EIM), as a potential electrolyte additive, has shown impressive application prospects in several research projects. The following are the main application status and development trends of EIM in lithium battery electrolytes.

1. As an electrolyte additive

EIM was mainly used as an additive when it was introduced into the lithium battery electrolyte system. Studies have shown that adding EIM in moderation can significantly improve the conductivity and stability of the electrolyte. For example, after adding 1%-5% EIM to the carbonate electrolyte, the ionic conductivity of the electrolyte is increased by about 20%-30%, and the oxidative stability of the electrolyte is also significantly enhanced. This is because EIM can form hydrogen bonds or coordination bonds with anions in the lithium salt, changing the microstructure of the electrolyte, thereby promoting the dissociation and migration of lithium ions.

In addition, EIM can improve interfacial compatibility between the electrolyte and the electrode material. Experimental results show that in the electrolyte containing EIM, the surface morphology of the positive electrode material is more uniform, the utilization rate of active substances is higher, and the charging and discharging efficiency of the battery is also improved. Especially for high-nickel ternary cathode materials (such as NCM811), the addition of EIM can effectively suppress the occurrence of side reactions and extend the cycle life of the battery.

2. As a functional solvent

In addition to being an additive, EIM can also be used directly as a functional solvent, replacing traditional carbonate solvents. Compared with traditional solvents, EIM has lower viscosity and higher flash point, and can maintain good fluidity over a wider temperature range, especially suitable for lithium batteries in high temperature environments. Studies have shown that EIM-based electrolytes can maintain high ionic conductivity and stability under high temperature conditions above 60°C, while traditional carbonate electrolytes often suffer performance degradation due to decomposition at this temperature.

In addition, EIM has better wetting properties, which can better wet the electrode material and reduce the contact resistance between the electrode and the electrolyte. This is particularly important for improving the battery’s rate performance and low temperature performance. The experimental results show that EIM is usedThe lithium battery as a solvent can still maintain a capacity retention rate of more than 80% in a low temperature environment of -20°C, while the capacity retention rate of traditional electrolyte batteries is only about 50%.

3. As a solid electrolyte component

With the rapid development of solid-state lithium battery technology, the application of EIM in solid-state electrolytes has also attracted widespread attention. As an organic small molecule, EIM has high flexibility and good film formation. It can form composite materials with inorganic solid electrolytes (such as LiPON, LLZO, etc.), improving the mechanical strength and ionic conductivity of the solid electrolyte. Research shows that by mixing EIM with inorganic solid electrolytes, a composite solid electrolyte with high ionic conductivity and good mechanical properties can be prepared, which is suitable for all-solid lithium batteries.

In addition, EIM can also be combined with polymer electrolytes (such as PEO, PVDF, etc.) to form a quasi-solid electrolyte. This type of electrolyte not only has high ionic conductivity, but also has good flexibility and processability, and can maintain stable electrochemical properties under large deformation. Experimental results show that EIM-based quasi-solid electrolytes can still maintain good conductivity and interface stability under extreme conditions such as bending and folding, and are suitable for lithium batteries in flexible electronic devices and wearable devices.

2-Advantages of ethylimidazole in lithium battery electrolytes

2-ethylimidazole (EIM) has attracted widespread attention in the field of lithium battery electrolytes mainly because it shows significant advantages in many aspects. The advantages of EIM will be discussed in detail from three aspects: electrochemical performance, safety and cost-effectiveness.

1. Excellent electrochemical performance

The application of EIM in lithium battery electrolytes has greatly improved the electrochemical performance of batteries, which is specifically reflected in the following aspects:

Wide electrochemical window: The electrochemical window of EIM is wide, usually between 3.0-5.0 V, and can be suitable for high-voltage lithium battery systems. This makes EIM an ideal electrolyte additive for high voltage positive electrode materials (such as NCM811, NCA, etc.), helping to increase the energy density of the battery.
High ionic conductivity: EIM can form hydrogen bonds or coordination bonds with anions in lithium salts, change the microstructure of the electrolyte, and promote the dissociation and migration of lithium ions. Research shows that the ionic conductivity of electrolytes containing EIM is 20%-30% higher than that of traditional electrolytes, thereby reducing the polarization phenomenon inside the battery and improving the overall performance of the battery.
Good interface compatibility: EIM can form a stable solid electrolyte interface (SEI) film on the electrode surface, effectively inhibiting the occurrence of side reactions, especially lithium dendrites.Grow. This not only improves the safety of the battery, but also extends the cycle life of the battery. Experimental results show that electrolytes containing EIM can keep the battery at a high capacity retention rate after thousands of cycles.
Excellent low-temperature performance: EIM has a low glass transition temperature (Tg) and can maintain good fluidity in low-temperature environments. This is crucial to improving the performance of lithium batteries under low temperature conditions. Studies have shown that lithium batteries using EIM as solvent can still maintain a capacity retention rate of more than 80% in a low temperature environment of -20°C, while the capacity retention rate of traditional electrolyte batteries is only about 50%.

2. Significantly improved safety

The safety of lithium batteries has always been the focus of industry attention, especially in electric vehicles and energy storage systems. The safety of batteries directly affects the reliability and service life of the entire system. The application of EIM in lithium battery electrolytes has significantly improved the safety of the battery, which is specifically manifested as:

Inhibit the growth of lithium dendrites: EIM can form a stable SEI film on the surface of the lithium metal negative electrode, effectively inhibiting the growth of lithium dendrites. Lithium dendrites are one of the main causes of battery short circuit and thermal runaway, so the addition of EIM can significantly reduce the risk of safety accidents in batteries.
Improving Thermal Stability: EIM has high thermal stability and chemical stability, and can maintain good physical and chemical properties over a wide temperature range. This allows the electrolyte containing EIM to maintain stable electrochemical properties under high temperature environments, avoiding the safety hazards caused by the decomposition of traditional electrolytes at high temperatures.
Reduce volatility and flammability: Compared with traditional carbonate solvents, EIM has lower volatility and higher flash point, and is less prone to combustion and explosion. This makes the application of EIM in electrolytes greatly reduces the safety risks of batteries under high temperature or overcharge conditions.

3. Significant cost-effective

In addition to its advantages in electrochemical performance and safety, EIM also performs excellent in cost-effectiveness. Specifically reflected in the following aspects:

Easy to obtain raw materials: The synthesis process of EIM is relatively simple, with a wide range of raw materials and a low price. Compared with some complex organic electrolyte additives, EIM has obvious cost advantages and is suitable for large-scale industrial production.
Small amount and good effect: EIM as an efficient electric power supplyDetection additives can significantly improve the performance of the electrolyte by adding a small amount. This not only reduces material costs, but also reduces the complexity of the production process and improves production efficiency.
Extend battery life: EIM can effectively suppress the occurrence of side reactions and extend the battery’s cycle life. This means that maintenance and replacement costs will be greatly reduced throughout the battery life, thereby improving the economics of the battery.

2-Challenges and Coping Strategies of Ethylimidazole in Lithium Battery Electrolyte

Although 2-ethylimidazole (EIM) shows many advantages in lithium battery electrolytes, it still faces some challenges in practical application. In order to fully realize the potential of EIM, researchers need to propose effective response strategies to these issues. Here are several major challenges and solutions faced by EIM in lithium battery electrolytes.

1. Solubility issues

EIM has good chemical stability and electrochemical properties, but its solubility in some organic solvents is low, especially when crystallization is easily precipitated at high concentrations. This not only affects the uniformity and stability of the electrolyte, but may also lead to local current unevenness in the battery, which in turn affects the performance of the battery.

Coping strategies:

Optimize solvent system: By selecting the appropriate co-solvent, the solubility of EIM can be effectively improved. Studies have shown that adding a small amount of high-polar solvents (such as DMC, EC) or low-polar solvents (such as FEC, VC) can significantly improve the solubility of EIM in the electrolyte. In addition, it is also possible to consider using an ionic liquid as a co-solvent to further improve the solubility of EIM and the stability of the electrolyte.
Adjust the concentration of EIM: Reasonably control the amount of EIM added according to different application scenarios. Generally speaking, the amount of EIM should not be too high, and it is usually more suitable between 1% and 5%. Excessive concentrations not only increase the risk of precipitation of EIM, but may also affect other performance indicators of the electrolyte, such as viscosity and ionic conductivity.

2. Interface compatibility issues

Although EIM can form a stable SEI film on the electrode surface, in some cases, there are still certain problems with the interface compatibility between the EIM and the electrode material. For example, EIM may react sideways with certain high-nickel ternary positive electrode materials, resulting in poor passivation layers on the electrode surface, affecting the battery charge and discharge efficiency and cycle life.

Coping strategies:

Develop new electrode materials: By improving the surface structure of the electrode material or introducing a functional coating, the interface compatibility between the EIM and the electrode material can be effectively improved. For example, using nanoscale positive electrode materials or coating a thin layer of conductive polymer (such as PEDOT-PSS) on its surface can reduce the side reaction between EIM and the electrode material and improve the overall performance of the battery.
Optimize electrolyte formula: Interface compatibility between EIM and electrode material can be improved by adjusting other components in the electrolyte. For example, adding an appropriate amount of fluorocarbonate additives (such as FEC, FEMC) can enhance the interaction between EIM and the electrode material, promote the formation of SEI films, and reduce the occurrence of side reactions.

3. Long-term stability issues

EIM has high thermal and chemical stability, but during long-term use, there may still be certain decomposition or aging phenomena, especially under high temperature or high voltage conditions. This will not only affect the performance of the battery, but may also lead to safety issues.

Coping strategies:

Introduce antioxidants: By adding an appropriate amount of antioxidants (such as BHT, THF) to the electrolyte, it can effectively inhibit the decomposition and aging of EIM and extend the service life of the battery. Studies have shown that adding 0.1%-0.5% antioxidants can significantly improve the stability of electrolytes containing EIM under high temperature conditions and reduce the capacity attenuation of the battery.
Optimize battery packaging technology: By improving the battery packaging technology, it can effectively prevent the impact of the external environment on EIM and extend the battery’s service life. For example, using aluminum-plastic film or ceramic separator with better sealing can reduce the invasion of oxygen and moisture, prevent EIM from reacting with oxygen in the air, thereby improving the long-term stability of the battery.

4. Cost and large-scale production issues

Although EIM’s raw materials are easy to obtain and the synthesis process is relatively simple, in large-scale industrial production, they still face problems of cost and output. Especially for some high-end applications (such as electric vehicles and energy storage systems), the production cost and supply capacity of EIM will become the key factors that restrict its widespread use.

Coping strategies:

Optimize synthesis process: By improving the synthesis process of EIM, production costs can be reduced and output can be increased. For example, using a continuous flow reactor instead of a traditional batch reactor can achieve efficient synthesis and large-scale production of EIM. In addition, it can also be optimized by optimizing reaction conditions (such as temperature, pressure, urging, etc.) and further improve the yield and purity of EIM.
Build supply chain cooperation: Establish close cooperative relationships with upstream suppliers to ensure stable supply of EIM. At the same time, the production cost of EIM can be reduced through joint research and development and technology transfer, and promoted its widespread application in lithium battery electrolytes.

Future development direction and prospect

2-ethylimidazole (EIM) has broad application prospects in lithium battery electrolytes, but there are still many directions worthy of in-depth research. In the future, scientific researchers can further explore the application potential of EIM from the following aspects and promote the development of lithium battery technology.

1. Development of new electrolyte systems

With the continuous expansion of lithium battery application scenarios, traditional electrolytes have been unable to meet the growing performance needs. Therefore, the development of new electrolyte systems has become a hot topic in current research. As a multifunctional organic compound, EIM can play an important role in different types of electrolyte systems. Future research can focus on the following directions:

High voltage electrolyte: With the widespread application of high-voltage positive electrode materials (such as NCM811, NCA, etc.), it is particularly urgent to develop electrolytes suitable for high-voltage lithium batteries. EIM has a broad electrochemical window, which can effectively inhibit the oxidation and decomposition of positive electrode materials, and is expected to become an ideal additive for high-voltage electrolytes.
Low-temperature electrolytes: In cold areas or low-temperature environments, the performance of lithium batteries is often limited. EIM has a low glass transition temperature (Tg) that maintains good fluidity under low temperature conditions, helping to develop high-performance electrolytes suitable for low temperature environments. Future research can further optimize the synergistic effect of EIM and other low-temperature additives and improve the low-temperature performance of electrolytes.
Solid-state electrolyte: Solid-state lithium batteries are considered to be an important development direction for the next generation of lithium batteries, with higher safety and energy density. As an organic small molecule, EIM has good flexibility and film formation, and can form composite materials with inorganic solid electrolytes or polymer electrolytes, thereby enhancing the mechanical strength and ionic conductivity of the solid electrolytes. Future research can explore more application possibilities of EIM in solid-state electrolytes and promote the commercialization of all-solid-state lithium batteries.

2. Interface engineering and material modification

Interface problems are one of the key factors affecting the performance of lithium batteries. EIM can form a stable SEI film on the electrode surface, effectively suppressing the occurrence of side reactions, but its interface compatibility with the electrode material still needs to be improved.One-step optimization. Future research can focus on the following directions:

Interface Modification: By introducing a functionalized coating or modification layer on the electrode surface, the interface compatibility between the EIM and the electrode material can be further improved. For example, using nanoscale positive electrode materials or coating a thin layer of conductive polymer (such as PEDOT-PSS) on its surface can reduce the side reaction between EIM and the electrode material and improve the overall performance of the battery.
Material Modification: By modifying the electrode material, the interaction with EIM can be enhanced and the formation of SEI film can be promoted. For example, using doping and coating can improve the surface activity and stability of the electrode material, reduce the decomposition of EIM on the electrode surface, and extend the cycle life of the battery.

3. Design of multifunctional electrolyte additives

In order to further improve the comprehensive performance of lithium batteries, future electrolyte additives must not only have a single function, but also have multiple synergistic effects. As a versatile organic compound, EIM has demonstrated excellent conductivity, interface compatibility and safety in electrolytes. Future research can further explore the synergy between EIM and other additives to design composite electrolyte additives with multiple functions. For example, combining EIM with fluorocarbonate additives (such as FEC, FEMC) can simultaneously improve the conductivity and interface stability of the electrolyte; combining EIM with antioxidants (such as BHT, THF) can simultaneously improve the thermal stability of the electrolyte; combining EIM with antioxidants (such as BHT, THF) can simultaneously improve the thermal stability of the electrolyte. and long-term stability.

4. Promotion of industrial production

Although EIM has shown many advantages in the laboratory, it still faces some challenges in large-scale industrial production. Future research needs to focus on the following aspects:

Optimize synthesis process: By improving the synthesis process of EIM, production costs can be reduced and output can be increased. For example, using a continuous flow reactor instead of a traditional batch reactor can achieve efficient synthesis and large-scale production of EIM. In addition, the yield and purity of EIM can be further improved by optimizing reaction conditions (such as temperature, pressure, catalyst, etc.).
Build supply chain cooperation: Establish close cooperative relationships with upstream suppliers to ensure stable supply of EIM. At the same time, the production cost of EIM can be reduced through joint research and development and technology transfer, and promoted its widespread application in lithium battery electrolytes.
