Formally referred to as a Safety Reinforced Layer (SRL), the composite material measures just one micrometer thick – or about 1/100th the thickness of a human hair. It is designed to sit between the cathode layer and the current collector (an aluminum foil that functions as a pathway for electrons) in a battery and acts as a temperature-sensitive fuse.
very interesting. I’m sure someone will be along to tell me why I shouldn’t care.
Not enough people on here for that yet.
