Abstract

See full text

A non-aqueous electrolyte battery which exhibits satisfactory reliability because reduction in the discharge capacity can be significantly prevented even after use with rapid temperature change and which enables excellent productivity to be realized. The non-aqueous electrolyte battery includes a cathode and an anode in which an active material for the cathode and/or an active material for the anode is integrated by a binder, wherein the binder for the cathode and/or the binder for the anode is a mixture of polyimide, which is soluble in an organic solvent, and a fluorine polymer. The polyimide is expressed by the following formula: ##STR1##
