System, method, and apparatus for battery protection
A battery protection system comprises sleeves, carbon fibers, a case, and liquid. The sleeves are hollow for insertion of battery cells. The carbon fibers are disposed on outer surfaces of the sleeves. The case houses the sleeves and has an inner cavity. The liquid and the carbon fibers are disposed in the inner cavity, where the carbon fibers are exposed to the liquid.
