Fire-Resistant Materials & EV Battery Safety
The Risk of EV Battery Fires
It is crucial to understand the causes of EV battery fires. Such fires are often rapid and spread quickly. Many reports indicate that battery fires usually occur during or shortly after charging. Collisions can damage the battery and cause short circuits. Sometimes, chemical reactions in damaged cells can ignite other nearby cells. The main causes are as follows:
Charging Accidents: More than one-third of EV fires occur during or shortly after charging.
Battery Damage: Collisions may lead to internal short circuits in the battery.
Thermal Runaway: A problem with one cell may cause other cells to catch fire.
When thermal runaway occurs, the temperature of the battery becomes extremely high. Refer to the table below to understand the high temperatures a battery may reach:
|
Temperature Range (°C) |
Description |
|
150 - 200 |
The battery may reach these temperatures during thermal runaway. At such high temperatures, the organic electrolyte decomposes and releases energy and flammable gases. |

Why Fire-Resistant Materials Are Critical
Even in unexpected situations, you want your EV to be safe. Fire-resistant materials help stop and control battery fires. These materials prevent heat and flames from spreading between cells. For example, Fuji Juli's G1S20488 is used as a shield; it blocks heat, helping to stop chain reactions. G1S20360 helps prevent fire ignition and spread.
Fire-resistant materials also assist firefighters in handling EV fires. Fire blankets can slow down or stop thermal runaway before water is used. Studies have shown that agents such as BIOVERSAL and COG work well on lithium-ion battery fires. These fire extinguishers help put out fires more easily while protecting people and vehicles.
Your EV needs fire-resistant materials because they reduce the risk of fire and help ensure your safety. These materials give you more time to act and also help first responders work more effectively.
Types of Fire-Resistant Materials in EVs
Mica Tapes and Sheets
Mica tapes and sheets are widely used in EV battery packs. These materials can withstand extremely high temperatures. Muscovite can tolerate a maximum temperature of 800°C, while phlogopite can withstand temperatures exceeding 1000°C. Mica remains strong and retains its shape when heated. In addition, it has excellent electrical insulation performance, which means it can effectively block high voltage and prevent leakage. This helps ensure battery cells are protected from short circuits. Mica does not decompose when in contact with chemicals, so it has a longer service life in harsh battery environments.
Tip: Mica is moderately priced but offers excellent heat resistance and strong insulation performance.

Flame-Retardant Fabrics and Other Options
There are other fire-resistant materials used in EVs. Some examples include flame-retardant fabrics, ceramic blankets, aerogels, and special coatings. Aerogels are very lightweight and do not conduct heat easily, helping to prevent heat diffusion between battery cells. Ceramic blankets have excellent fire resistance but are heavier than aerogels. Silicone is another material that can withstand high temperatures, making the battery safer. In addition, composite materials such as glass fiber-reinforced plastics make the battery case lighter and safer.
Aerogels are efficient insulators and lighter than mica.
Although ceramic blankets are heavier, they still provide fire protection.
Silicone and composite materials help make batteries safer and lighter.
Comparing Material Performance
You may want to know the differences between these materials. Mica has excellent insulation performance, with an insulation strength of 50 to 150 kV per millimeter, and can withstand temperatures up to 1200°C. Ceramics also have excellent insulation performance and perform well in high-voltage environments. Although aerogels are effective insulators, their insulation performance may not be as good as that of mica. Lightweight materials such as composites and aerogels can make batteries safer and more efficient.

Mica sheets are specially made to withstand high temperatures. They slow down the spread of heat in the battery pack, giving you and first responders more time in case of a fire. Mica also has excellent chemical stability and will not decompose even when in contact with battery electrolytes or gases. This helps extend the battery's service life while keeping you safer.
Note: By slowing down heat diffusion, mica sheets can give you more time to escape. This is really helpful in emergency situations.
Application in Battery Design
You can find mica in many parts of EV batteries. Manufacturers attach mica tapes and sheets between battery cells and above cell vents. This prevents heat and flames from spreading to other cells. Mica is flexible, so it is suitable for batteries of different shapes, including cylindrical, prismatic, and pouch batteries. Because mica can fit tightly into narrow spaces, it provides better safety.
Mica is tough and durable; it continues to work even when your car is bumpy or experiences temperature changes. You don't have to worry about insulation failure. Mica helps prevent short circuits and effectively blocks high-voltage leakage. You can find mica where fire-resistant materials are most needed, such as near battery vents and between cells.
Mica tape is wrapped around battery cells to provide additional insulation protection.
Sheets cover cell vents to block heat and flames.
Flexible mica can be applied to narrow spaces and irregular shapes.
Using mica results in a safer battery pack. It effectively protects against fires, high temperatures, and chemical damage. You can rely on mica to ensure the safety of your EV battery.

Choosing Fire-Resistant Materials for EVs
Key Factors for Manufacturers
You want your EV to be safe, reliable, and high-performing. Manufacturers consider many factors when selecting fire-resistant materials. Battery design is crucial. If there are narrow or irregular spaces inside the battery pack, flexible materials like mica work best. Some batteries adopt a honeycomb sandwich structure, which requires materials that are both rigid and effective at blocking heat transfer.
Manufacturers also pay attention to how the battery performs in collisions. They use computer models to test what happens during a collision. Once impacted, the material must remain strong and not deform. The table below shows what manufacturers focus on when selecting fire-resistant materials:
