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

For example: Tesla model3 battery PACK package In order to reduce the weight of the module and improve the safety, a large amount of silicone foam potting material is used to protect a single battery core, which can prevent the heat transfer from the upper part of the battery pack to the battery core within a certain period of time. The heat is out of control. Due to the convenient benchmarking of the power battery technology, Tesla has greatly accelerated the application of silicone foaming materials in the power battery PACK package.
At present, there are mature liquid silicone foamed silica sheets with mature performance.
At the same time, foamed silica gel is widely used for anti-leakage, dust-proof, shock-absorbing, and air-tight treatment around LEDs; as well as anti-noise around the speakers and speakers, and filling gaps.
