Recently, a well-known domestic research institution and automobile manufacturing enterprise jointly announced the successful application of ethyl silicone oil in the heat dissipation system of new energy vehicle power batteries, significantly improving the stability and safety of battery operation in high temperature environments. This breakthrough provides a new solution for the technological upgrading of the new energy vehicle industry.


Ethyl silicone oil has become the core material for optimizing the heat dissipation system due to its excellent thermal stability, low volatility, and good insulation performance. The research team has developed a new type of ethyl silicone oil based thermal conductive medium through molecular structure design and modification technology. Its thermal conductivity is 30% higher than traditional materials, and it has stronger high-temperature resistance, which can work stably in a wide temperature range of -50 ℃ to 250 ℃.


In actual testing, the new energy vehicle battery pack equipped with this cooling system showed a surface temperature reduction of 15 ℃ compared to traditional solutions under continuous high-intensity operation, effectively extending the battery life and reducing the risk of thermal runaway. At present, this technology has passed rigorous testing by multiple car companies and is expected to gradually be applied to mass-produced models in the next two years, providing more reliable technical support for the popularization of new energy vehicles.


Industry experts say that the innovative application of ethyl silicone oil in the field of new energy not only solves the key problem of heat dissipation in power batteries, but also opens up a new path for the high-end development of organic silicon materials. With the further maturity of technology, ethyl silicone oil is expected to play a greater role in energy storage, electronic device heat dissipation, and other fields.
