Organosilicon materials help the rapid development of new energy vehicles

Silicone has a Si-O bond as the main chain structure, and the side chain is connected to various other organic groups through silicon atoms. The bond energy of the Si-O bond in organic silicon is much greater than that of the C-C bond, so the thermal stability of organic silicon products is high, and the chemical bonds of the molecules will not break or decompose at high temperatures (or radiation exposure).

Therefore, it can withstand high and low temperatures and can be used in a wide temperature range; at the same time, the main chain has no double bonds and is not easily decomposed by ultraviolet light and ozone; the special composition and molecular structure make the organic silicon material combine organic and inorganic materials All-in-one, with excellent high and low temperature resistance, weather resistance, electrical insulation, biocompatibility, etc. This point is unmatched by other materials.

As the power source of new energy vehicles, batteries, in addition to positive electrode materials, negative electrode materials, separators, electrolytes and other battery raw materials that affect their performance, temperature changes, vibrations, and moisture during the driving of new energy vehicles will also change the battery performance. In turn affect its endurance. With its superior performance, Organosilicon materials can help new energy vehicles to better release performance.

temperature control

The carbonate in the lithium battery electrolyte has a relatively 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.
High-end customized silicone materials can effectively dissipate heat for battery packs and cells, and improve battery operating temperature. At the same time, high-end organic silicon materials can form a heat shield around the battery core in the battery pack. When the environment is too cold or too hot, the battery can still maintain efficient operation.


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

In this regard, silicone material manufacturers provide a "battery pack exclusive customization" silicone solution solution to protect the durability of the battery.


Another challenge facing electric vehicle batteries lies in short-circuit and over-current, and the insulation of organic silicon materials appropriately addresses this problem.

The application of silicone in the battery can well protect the internal key electronic devices, batteries and bus bars, thereby avoiding the risk of power surges and battery fire.
