UL 1971 Thermal Runaway Protection Coated by Retardant Catalyst 1028 and Solid-State Battery Separator
Introduction: A Revolution about Security
In the field of new energy, battery safety has always been a core issue that consumers and manufacturers are concerned about. Just imagine what kind of disaster would it be if a cell phone, laptop or electric car suddenly caught fire or even exploded? It’s like putting a time bomb in your pocket or driving a car that can “self-destruct” at any time. To solve this problem, scientists have been looking for safer battery solutions, and solid-state batteries are highly expected for their high safety.
However, even with solid-state batteries, we still have to face a key challenge – Thermal Runaway. Thermal runaway is like a “volcanic eruption” inside the battery. Once triggered, it may lead to an uncontrollable increase in temperature, which will eventually cause a fire or even an explosion. To cope with this risk, delay catalyst 1028 came into being. It is a special chemical material that can effectively delay the occurrence of thermal runaway and win valuable escape time for users. More importantly, this catalyst can be perfectly combined with the coating process of solid-state battery separators, thereby improving the safety of the entire battery system.
So, how exactly does the delay catalyst 1028 work? How did it pass the UL 1971 standard test? This article will explore the mystery of this innovative material from multiple angles such as technical principles, application scenarios, product parameters, and domestic and foreign research progress. Whether you are a professional in the battery field or an ordinary reader interested in new energy technology, this article will unveil the mystery of delay catalyst 1028 for you.
Technical Principle: Secret Weapon of Delay Catalyst 1028
The delay catalyst 1028 is a chemical material specially designed to inhibit thermal runaway from the battery. Its core role is to reduce the probability of thermal runaway and prolong its triggering time through a series of complex chemical reactions. To better understand this process, we need to first understand the basic mechanisms of thermal runaway.
The formation mechanism of thermal runaway
Thermal runaway usually occurs when the battery is short-circuited or overcharged. When too much heat is generated inside the battery, the electrolyte will quickly decompose and release a large amount of gas, causing the temperature to rise further. This positive feedback cycle may eventually cause the power cell to rupture, catch fire or even explode. In short, thermal runaway is like an uncontrollable “chemical avalanche”.
The mechanism of action of delayed catalyst 1028
The delay catalyst 1028 delays the occurrence of thermal runaway in the following ways:
-
Absorb heat
The delay catalyst 1028 has a high thermal capacity and canA large amount of heat is absorbed in a short period of time, thereby slowing down the temperature rise. This is like pouring a bucket of cold water on a hot stove. Although it cannot completely extinguish the flame, it can at least temporarily suppress the fire. -
Inhibition of side reactions
During thermal runaway, the electrolyte decomposition will produce a variety of harmful gases, which will accelerate the temperature increase. The delay catalyst 1028 can inhibit the occurrence of these side reactions and reduce the amount of gas generation through chemisorption or catalytic action. -
Enhance the stability of the diaphragm
The solid-state battery separator is an important part of the battery’s interior, responsible for separating the positive and negative electrodes and allowing lithium ions to pass through. However, under high temperature conditions, conventional diaphragms may lose their mechanical strength or even melt, resulting in short circuits. The delay catalyst 1028 is uniformly covered on the surface of the membrane through the coating process, which significantly improves the heat resistance and short-circuit resistance of the membrane. -
Promote heat dissipation
The delay catalyst 1028 also has certain thermal conductivity, which can quickly transmit locally accumulated heat to other areas, avoiding the concentrated chain reaction of hot spots.
Chemical reaction process
The following is a typical chemical reaction equation for delayed catalyst 1028 under thermal runaway conditions (taking lithium-ion batteries as an example):
-
Electrolytic solution decomposition inhibits reaction
[
C_xH_y + 1028 rightarrow text{stable intermediate product} + text{small amount of gas}
] -
Heat absorption reaction
[
1028 + Q rightarrow text{active substance} + Delta H
]
Where (Q) represents the input heat and (Delta H) represents the absorbed heat. These reactions not only reduce system temperature, but also reduce the generation of harmful gases, thus buying more time for subsequent safe handling.
Application Scenario: A leap from the laboratory to the real world
The delay catalyst 1028 has a wide range of applications, covering almost all battery scenarios that require high safety. Here are a few typical examples:
1. Consumer Electronics
Battery safety is crucial for portable devices such as smartphones, tablets and laptops. The delay catalyst 1028 can effectively prevent thermal runaway caused by drop, squeeze or overcharge, and ensure the safety of users in daily use.
2. Electric transportation
Electric vehicles and electric bicycles have developed rapidly in recent years, but the subsequent battery safety risks are becoming increasingly prominent. By applying the delay catalyst 1028 to the solid-state battery separator, the overall safety of the battery pack can be significantly improved and the possibility of accidents can be reduced.
3. Industrial energy storage system
Large energy storage power stations usually require thousands or even tens of thousands of batteries. Once the heat is out of control, the consequences will be unimaginable. The delay catalyst 1028 can help these systems establish a stronger firewall to ensure the sustained and stable power supply.
4. Special environment application
In aerospace, deep-sea detection and extreme climate conditions, batteries must not only withstand harsh environments such as high voltage and low temperature, but also meet extremely high safety requirements. The delay catalyst 1028 is equally outstanding in these fields due to its outstanding performance.
Product parameters: The truth behind the data

UL 1971 Test: Safety Touchstone
UL 1971 is one of the widely recognized standards for thermal runaway protection of batteries worldwide. The standard is designed to evaluate the safety performance of the battery under extreme conditions, ensuring that it can provide users with sufficient time to evacuate or take emergency measures after an accident.
Test content
According to the requirements of UL 1971, the delay catalyst 1028 needs to pass the following rigorous tests:
-
Acupuncture test
Punch a steel needle with a diameter of 1mm into the center of the battery at a certain speed to simulate the internal short circuit. The test results show that the battery added to the delayed catalyst 1028 only showed a slight temperature rise after the needle puncture and no obvious thermal runaway occurred. -
Overcharge test
Charge the battery beyond its rated capacity and observe whether it will catch fire or explode. Experimental data show that delayed catalyst 1028 can significantly extend the time when overcharge causes heat out of control, providing sufficient buffering period for the system to power outage. -
High temperature storage test
Store the battery in a constant temperature environment of 60°C for 7 consecutive days to check its performance changes. The results show that the delay catalyst 1028 coating effectively protects the membrane structure and avoids performance attenuation caused by high temperature. -
External fire test
Directly ignite the outside of the battery with an open flame, and record its combustion time and flame propagation speed. Tests found that the battery containing the delay catalyst 1028 can still maintain a stable state for a long time under fire conditions.
Test results
After the above multiple tests, the delay catalyst 1028 has successfully passed the UL 1971 certification, proving its excellent performance in battery thermal runaway protection.
