Description

technical field [0001] The invention belongs to the technical field of silica gel polymer materials, and relates to an insulating silica gel material and a silica gel cloth for a new energy vehicle battery heating sheet containing the material. Background technique [0002] Nowadays, all new energy electric vehicles such as electric vehicles and electric bicycles are powered by the process of battery energy storage and release, but the efficiency of chemical batteries is very closely related to the environment, especially the speed of chemical reactions is closely related to temperature. In winter, especially in northern regions, when the ambient temperature is very low, starting the vehicle after the battery is fully charged may only cover half the kilometers in summer. But by heating the battery so that it is used at the optimum energy conversion temperature, the efficiency of battery usage can be maximized. Therefore, in the severe cold season, it is often necessary to h...
