Abstract
A zinc-based battery includes a non-sintered separator system including a polymer separator and a coating on the polymer separator. The coating includes cellulose acetate that prevents metallic zinc penetration into the separator, and ceria bound with the cellulose acetate that chemically oxidizes metallic zinc to zinc oxide.
