Abstract

An improved cathode film is formed by forming a copolymer of 10 to 90 mol percent of a fluorinated ethylene copolymer such as tetrafluoroethylene soluble in an organic solvent such as acetone. An ionically conductive salt such as potassium trifluorosulfonate is added to a solution of the copolymer. The solution is applied to particles of active cathode material such as AgO. The solvent is removed to form a film which can be pressed onto a current collector.
