Structure and function of flexible battery current collector
As a new energy storage device, flexible batteries are one of the core components of the current collector. The current collector acts like a blood vessel network in the human body, which is responsible for transporting current from the inside of the battery to external circuits. To achieve this function, the current collector must have a series of key characteristics such as high conductivity, good mechanical strength and excellent flexibility.
Basic composition and material selection of current collector
The current collector of a flexible battery is usually composed of two parts: a conductive substrate and a surface coating. Conductive substrates generally use metal foils (such as copper or aluminum foils) because they have excellent conductivity and relatively low cost. However, pure metal foils have shortcomings in flexibility and therefore require a special layer of material to be applied to its surface to enhance overall performance. This coating has become a stage for trimethylhydroxyethyldiamine ethyl ether to show off its strengths.
The influence of material properties on performance
The reason why trimethylhydroxyethyl bisaminoethyl ether can play a role in flexible battery current collectors is mainly due to its unique componentSubstructure and chemical properties. First, the amino and hydroxyl groups in their molecules can form a strong chemical bond with the metal surface, thereby significantly improving the adhesion of the coating. Secondly, the ether bond structure of the compound imparts excellent flexibility and tear resistance to the coating, allowing the current collector to remain intact during repeated bending. Afterwards, its good conductivity ensures that the current transmission efficiency is not affected.
Special application in flexible batteries
In practical applications, trimethylhydroxyethylbisaminoethyl ether is usually sprayed in solution or immersed on the surface of metal foil, and after drying and curing, it forms a uniform coating. This process not only simplifies the production process, but also effectively reduces material losses. More importantly, the modified current collector can better adapt to the working environment of the flexible battery, and maintain stable performance regardless of extreme temperature changes or frequent mechanical stresses.
From the above analysis, it can be seen that the application of trimethylhydroxyethyl bisaminoethyl ether in flexible battery current collectors is by no means accidental, but an inevitable choice based on its excellent performance. It is precisely the existence of this material that allows flexible batteries to truly achieve the ideal state of “soft but not weak”.
Analysis of IEC 62133 Test Standard
Before discussing the performance of trimethylhydroxyethyl bisaminoethyl ether in flexible battery current collectors, we must first understand the 62133 test standards formulated by the International Electrotechnical Commission (IEC). This standard is an authoritative basis for evaluating the safety and reliability of secondary lithium batteries, covering all aspects from design verification to production control. Through a strict testing process, ensure that the battery can operate safely under all conditions.
Test project overview
IEC 62133 standard contains several critical tests, each of which is evaluated for the specific risks the battery may face. Here is a brief introduction to several major test projects:
- Short Circuit Test: Simulates the internal short circuit of the battery in extreme cases and detects whether there will be problems such as overheating or ignition.
- Overcharge test: Check the performance of the battery when charging exceeds the rated voltage to ensure that it does not cause safety hazards.
- Extrusion Test: Simulate the impact or extrusion of the battery by applying external pressure, and evaluate its structural integrity and safety.
- Drop Test: Test the performance changes of the battery after falling at different heights to verify its impact resistance.
- Thermal Abuse Test: Place the battery in a high temperature environment to observe its reactions to ensure that it can still work properly at extreme temperatures.
Testing Methods and Evaluation Standards
Each test itemThere are clear methods, steps and judgment criteria. For example, in short circuit test, the battery needs to be placed in a constant temperature box and connected to the positive and negative electrodes using low resistance wires for a duration of no less than 24 hours. If the battery does not catch fire, explosion or other dangerous conditions, it will be considered to have passed the test. Similarly, other test projects also have their own specific requirements and qualification conditions.
The role of trimethylhydroxyethylbisaminoethyl ether
Trimethylhydroxyethylbisaminoethyl ether plays an important role in these rigorous tests. Its unique molecular structure not only enhances the mechanical strength of the current collector, but also improves the heat resistance and chemical stability of the coating. Specifically manifested as:
- In short circuit test, effective protection of the coating reduces the corrosion rate of metal foil;
- In overcharge tests, the high conductivity of the material reduces the risk of heat accumulation;
- In extrusion tests, the flexibility of the coating helps absorb external pressure and avoid structural damage;
- In the drop test, the adhesion of the coating ensures good contact between the current collector and the electrode;
- In thermal abuse test, the material’s high temperature resistance ensures the stability of the coating under extreme conditions.
From the above analysis, it can be seen that the outstanding performance of trimethylhydroxyethyl bisaminoethyl ether in IEC 62133 test fully proves its important value in flexible battery current collector applications.
