Thermal cooling material for battery

     The thermal cooling of the battery is preferably a heat conducting phase change material. Thermal phase change is a kind of material that can absorb and release the latent heat of phase change. It has important applications in energy storage. Phase change materials have been paid more and more attention in the heat pipe force system of power battery.

     The thermal management technology of automotive battery using thermal conductive phase change materials has been widely studied. Using the phase change latent heat of phase change materials to control the temperature of the battery can effectively reduce the temperature rise of the battery under high rate working conditions and improve the temperature uniformity.

     Use phase change to absorb heat without significant change in its own temperature. Thermal conductive phase change materials are widely used in aerospace, building energy conservation, solar energy utilization, cold chain transportation and other fields.

      In the application case of battery thermal management, compare the advantages and disadvantages of air cooling, liquid cooling and phase change temperature control . Thermal conductive phase change materials have attracted much attention because of their excellent performance, high reliability and low cost. Gernally speaking, the maximum temperature that the battery needs to solve for heat dissipation does not exceed the working temperature and temperature uniformity. In order to make the battery play a good performance and prolong its service life, it is necessary to optimize the structure of the battery, increase cooling facilities, control the temperature environment of the battery operation, and the material with heat conduction phase change is conducive to the battery.
