Sailong aerogel film/pad is mainly used for insulation and flame retardancy between the battery cells in lithium-ion power batteries, as well as insulation and shock resistance between the module and the housing. In pursuit of volumetric energy density, lithium battery manufacturers do not leave much space for insulation layers between the battery cells. Aerogel, with its excellent flame retardant and insulation properties, as well as its low usage amount, has become the best choice for insulation materials in lithium battery cells.

Saolong aerogel film/pad is a composite insulation material made of silica aerogel and pre-oxidized silk, ceramic fibers, glass fibers, or other types of fibers. It is encapsulated with polymer films (PET, PI) or flame retardant coatings, and is formed through thermal pressing or coating techniques.
