This invention relates to a second 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 MXa, 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. |
