Absrtact: Moisture can cause the decomposition of lithium hexafluorophosphate in batteries to produce HF. Vibration may cause breakage of polar ears and short circuit of batteries. These most common factors may affect the life of batteries. In this regard, silicone material manufacturers provide "battery pack exclusive customization" solution of silicone solution, to protect the durability of batteries.

Silicone is mainly composed of Si-O bonds, and its side chains are connected with other organic groups through silicon atoms. The bond energy of Si-O bond in organosilicon is much larger than that of C-C bond, so the thermal stability of organosilicon products is high, and the chemical bond of molecule under high temperature (or irradiation) keeps splitting and not decomposing. Therefore, it can withstand high and low temperatures, and can be used in a wide temperature range; at the same time, there is no double bond in the main chain, and it is not easy to be decomposed by ultraviolet light and ozone; special composition and molecular structure make silicone materials have excellent high and low temperature resistance, weatherability, electrical insulation, biocompatibility and so on. Silicone materials have been widely used in civil areas such as architecture, electronics, electrical, chemical industry, and even in aviation, cutting-edge technology, military technology and other fields. For example, applications in extreme conditions of outer space, extremely cold Siberia or extremely hot Sahara desert can show excellent characteristics.

temperature control

Carbonate in the electrolyte of lithium batteries has a high melting point. Generally, when the temperature is below - 20 C, the batteries can not work properly. When the temperature is too high, the battery separator will melt and cause short-circuit and battery fire. Only when the appropriate temperature is maintained can the battery achieve its best performance. High-end customized silicone materials can effectively heat batteries and cores and improve the working temperature of batteries. At the same time, high-end organic silicon materials can form a thermal shield around the battery core in the battery pack. When the environment is supercooled or overheated, the battery can still operate efficiently.

Durability

In the daily use of new energy vehicles, humidity will cause the decomposition of lithium hexafluorophosphate in batteries to produce HF. Vibration may cause ear fracture, short circuit of batteries. These most common factors may affect the life of batteries. In this regard, silicone material manufacturers provide "battery pack exclusive customization" solution of silicone solution, to protect the durability of batteries.

Insulation

Another challenge facing EV batteries is short circuit and overcurrent, which is appropriately addressed by the insulation of silicone materials.  The application of silicone in batteries can protect key internal electronic devices, cores and buses, thus avoiding the risk of surge and battery fire.

As the power source of new energy vehicles, besides the influence of raw materials such as cathode material, negative material, diaphragm, electrolyte and so on, the temperature change, vibration, humidity and so on in the driving process of new energy vehicles will also change the performance of batteries, and then affect their endurance.

Scientists have made a lot of explorations on the application of silicone in new energy vehicles. As the leader of silicone industry, Zhaoshun Science and Technology has also proposed corresponding solutions for the application of new energy vehicles.
