Deterioration, graphite-polymer composites

A composite consisting of a mixture of carbon particles (e.g., carbon black or graphite) and a polymer binder such as polyethylene or polypropylene with a surface layer of a carbon-black or carbon-felt flow-through structure serves as the Br2 electrode in Zn/Br2 batteries. Because of the low surface area of the carbon-polymer surface, an additional layer of carbon is necessary to obtain higher reaction rates. The mechanical deterioration of graphite-polymer composite...
