Description
technical field [0001] The invention belongs to the technical field of heat-insulating materials, and relates to a high-temperature-resistant ultra-thin low-thermal-conduction heat-insulation material, and also relates to a preparation process of a high-temperature-resistant ultra-thin low-heat-conduction heat-insulation material. Background technique [0002] As a moving tool in human activities, automobiles have entered people's daily lives for hundreds of years. The power system of automobiles has also gradually entered the stage of new energy from traditional fossil fuels. Electric vehicles have been gradually put into the market because they are more environmentally friendly and energy-saving, and have received strong policy support from the state. [0003] How to ensure the safe use of the power battery system of electric vehicles during charging, discharging and operation, especially in extreme cases such as collisions and fires, thermal runaway will occur and spread ...
