<p><P>PROBLEM TO BE SOLVED: To provide a flat alkaline battery which is excellent in productivity, and allows the suppression of the post-discharge swelling of the battery. <P>SOLUTION: The flat alkaline battery comprises a positive electrode composed of a compact of a positive electrode mixture, a negative electrode including zinc or zinc alloy particles, a separator, and an alkaline electrolyte, which are all encased in a battery container including an exterior can, an aperture-sealing plate and a resin gasket. The positive electrode mixture contains manganese dioxide, at least one silver-containing material selected from the group consisting of silver oxide and silver-nickel complex oxide, and does not contain a resin binder, provided that the content of the manganese dioxide is larger than that of the silver-containing material. It is preferable for the flat alkaline battery that the positive electrode mixture compact has an outer peripheral part disposed between an inner surface of the exterior can and the resin gasket. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
