Abstract
Abstract This invention relates to a secondary battery comprised of a polymer film, and first and second collector plates. The polymer film comprises a polymer, a plasticizer for the polymer, an epoxidized vegetable oil, graphite and a salt disassociatingly solubilized by the plasticizer. The salt has the formula MX a , wherein X is chloride, bromide or iodide, M is a metal ion having a reduction-oxidation potential greater than that of X and a is the oxidation number of M.
