"A kind of heat insulation and buffer material widely used in modules and PACK, due to its porous structure, nanometer continuous network, and non-flammable, non-explosive, low thermal conductivity, high thermal insulation, high strength, at the same time, it is green and environmentally friendly, non-toxic, non-corrosive, acid and alkali resistant, and has excellent mechanical properties such as compression, seismic resistance, and sound insulation Compared with traditional thermal insulation materials, aerogel thermal insulation materials can achieve better thermal insulation effects with lighter weight and smaller volume, which is suitable for the field of thermal runaway management of lithium batteries and has great advantages. In addition, due to its excellent dielectric constant and high specific surface area, it has a broad prospect as a lightweight nanoporous material with a variety of high-quality properties and wide applications, and the product is widely used as a thermal insulation material in battery packs.
