Application of silicone foaming materials in new energy vehicles

Silicone foam material, 1 a kind of polymer material with siloxane as the main chain and organic groups in the side chain, plays an important role in many fields because of its unique properties. In recent years, with the rapid development of the new energy automobile industry, silicone foam materials have shown great application potential in this field due to their excellent temperature resistance, electrical insulation and flame retardancy.

In new energy vehicles, the battery is the core component that provides power. In order to protect the battery and improve the safety and service life, the thermal management in the battery management system is particularly critical. Silicone foam material has good thermal stability and can be used as a thermal insulation material for battery packs to effectively reduce the impact of ambient temperature on battery performance. At the same time, it can work stably in high temperature environments to ensure the safe operation of the battery.

Silicone foaming material has excellent flame retardant ability, with IPX8 waterproof rating and UL94V-0 fire rating, which can effectively block the intrusion of moisture and other harmful substances, so as to ensure the normal operation and safety of new energy vehicles in various environments. Fire rating: UL94V-0 

The key technology of new energy electric vehicles lies in the charging and discharging technology and safety performance of high energy density lithium batteries. Lithium batteries must maintain excellent waterproof and dustproof effects during use, and spontaneous combustion is the first problem that affects their safe use. Under extreme conditions such as heavy rain, shoals, and smog, in order to meet the requirements of sealing and buffering protection of power batteries during car driving, American car companies such as Tesla took the lead in applying the 1 material of foamed silicone to power batteries.

For example, in order to reduce the weight of the module and improve the safety of the Tesla model3 battery PACK package, a large number of silicone foam potting materials are used to protect a single battery cell, which can prevent the heat transfer from the upper part of the battery pack to the battery cell and cause thermal runaway within a certain period of time. Due to Tesla's role in the technical convenience of power battery packs, the application and promotion of silicone foam materials on power battery PACK packs are greatly accelerated. At present, there are mature and equivalent two-component liquid foaming silicone, liquid silicone foam and other materials.

With its excellent comprehensive performance, silicone foam materials are becoming an indispensable part of the development of new energy vehicles. It can not only improve the performance, safety and environmental protection of vehicles, but also provide innovation and progress for the new energy vehicle industry. Important support. With the progress of science and technology and the development of material science, the application of silicone foam materials in new energy vehicles will be more extensive in the future, and make greater contributions to the development of new energy vehicle industry.
