01      Good chemical stability

The alumina fiber composite has good acid and alkali resistance and other characteristics, which can adapt to different service environments and ensure the service life of the battery.

   02      Good impact resistance

In case of vehicle collision, the high strength of alumina fiber composite can resist the strong impact of the outside world and avoid mechanical damage, deformation and loosening of fastening parts.

   03      Good sealing performance

The physical and chemical properties of the alumina fiber composite are stable, and the designability is strong. When making the composite battery shell, the fireproof layer is added into the integrated molding, and the sealing performance is good. The thickness of the fireproof layer is<0.5mm, the mass of the fireproof layer is <0.5kg/m², and the temperature resistance is ≤ 1800 ℃.

   04      Lightweight

Under the premise of the same strength, the alumina fibre composite is lighter, which meets the development requirements of automobile lightweight and can greatly improve the endurance mileage of electric vehicles.
