The only power source for pure electric vehicles is the power battery pack, so the performance of the battery pack is particularly important. Lithium-ion batteries are widely used in electric or hybrid vehicles due to their high power density, high open-circuit voltage, low self-discharge, no memory, no pollution, and long cycle life. Since various electrochemical changes and physical changes occur during the charging and discharging process of the lithium-ion power battery, a large amount of heat is generated. If the heat is not dissipated during the driving process of the vehicle, it will cause heat generation and heat dissipation of the battery pack. The uneven distribution of the temperature field will eventually reduce the service life of the battery pack.

In the fields of new energy vehicles, photovoltaic and energy storage, the thermal management system can ensure that the products operate in a good temperature field. Effective thermal management is the main way to solve the damage of new energy products caused by temperature factors.

In addition to active cooling such as air cooling and water cooling, advanced thermal management materials, such as graphite sheet, thermal silicone pad and thermal gel, are also required to be used as auxiliary heat transfer media in the heat dissipation scheme to help realize a connected and fast heat dissipation path.
