<p><P>PROBLEM TO BE SOLVED: To provide an alkaline storage battery with improved reliability by increasing welding current flowing at a contact part of a collector and ends of an electrode, and reducing reactive current flowing in the collector to prevent the occurrence of short circuit at an electrode group through restraint of break or explosion of the collector. <P>SOLUTION: The alkaline storage battery includes a spiral electrode group 10a wound around in a spiral shape, and at the same time, a negative electrode collector 14 is welded to one of the electrode ends 12c of the electrode group 10a, and a positive electrode collector 15 is welded to the other electrode end 11c. Further, a conductive thin film 16 excellent in conductivity is arranged between one of the electrode ends 12c and the negative electrode collector 14, and another conductive thin film 16 excellent in conductivity is arranged between the other electrode end 11c and the positive electrode collector 15. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
