Abstract:
1. A film manganese battery, comprising: a sandwich consisting, in the listed order, of: a first polymer film; a cathode current collector; a manganese dioxide based cathode layer containing a binder mixture; a layer of electrolyte gel; a separator; a second layer of electrolyte gel; a zinc based anode layer containing the binder mixture; an anode current collector; a second polymer film; and a layer of adhesive interconnecting the first and second polymer films in a manner which hermetically connects the first and second polymer films to form a battery; and wherein: the binder mixture in the cathode layer and in the anode layer comprising polyvinyl pyrrolidone dissolved in dimethyl formamide in an amount of 0.2 to 10% by weight, based on the weight of the electrode layer, polyvinyl alcohol dissolved in distilled water in an amount of 0.05 to 10% by weight based on the weight of the electrode layer, and carboxymethyl cellulose is mixed in distilled water in an amount of 0.01 to 5% by weight, based on the weight of the electrode layer.
