Abstract

In a polymer electrolyte battery including a battery element having a cathode and an anode coiled through a polymer electrolyte, a section of the battery element perpendicular to the coiling axis has a curved form. As compared with a polymer electrolyte battery having a flat plate type battery element curved, the former battery has an extremely low possibility of short-circuit at the end of an electrode and excellent battery characteristics.
