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