According to SAGSI statistics, the average amount of silicone used in cars is about 1.2 kg/car.

The current outlet of the automobile industry lies in new energy vehicles, which is also the direction of future development. The market for plug-in hybrid vehicles and battery-powered electric vehicles (EV) is expected to grow exponentially in the next few years. But there are still many factors that can affect the realization of this potential, including the industry's ability to meet consumer expectations for performance and price. This will challenge battery manufacturers, prompting them to design smaller, lighter and cheaper high-capacity lithium battery products. Through better thermal control, these higher energy density battery packs can provide more sufficient and longer lasting energy. Manufacturers and designers of other EV components (including battery management systems, power control units, DC/DC converters, and electric motors) will face many of the same thermal management, assembly, and maintenance challenges. In view of the existing applications of silicone in the automotive industry, silicone practitioners have made a lot of explorations on whether it can be applied to power batteries.

Temperature control
The carbonate in the electrolyte of lithium batteries has a high melting point. Generally, when the temperature is lower than -20°C, the battery cannot work normally; when the temperature is too high, the battery diaphragm will melt and cause a short circuit to cause battery fire and other safety issues. Only by maintaining an appropriate temperature can the battery achieve its best performance.

Durability
During the daily use of new energy vehicles, moisture will cause the decomposition of lithium hexafluorophosphate in the battery to produce HF, vibration may cause problems such as breakage of the tabs and short-circuit of the battery. These most common factors can affect the battery life.

Insulation
Another challenge faced by electric vehicle batteries lies in short-circuit and over-current, and the insulating properties of organic silicon materials appropriately cope with this problem. The application of silicone in the battery can well protect the internal key electronic devices, batteries and bus bars, helping to avoid the risk of power surges and battery fires.
