<P>PROBLEM TO BE SOLVED: To provide an alkaline dry battery restrained from drying-up of electrolyte liquid of a gelatinous anode at the last period of charging, with improved strength of a cathode mixture, excellent in a preservation property by restraining self-discharge caused by nickel oxyhydroxide. <P>SOLUTION: The cathode mixture of the alkaline dry battery comprises manganese dioxide and nickel oxyhydroxide as activators, graphite as conductive agent, polyethylene as binder, the electrolyte, and at least one kind of additives selected from ZnO, Ca(OH)<SB>2</SB>, and Y<SB>2</SB>O<SB>3</SB>. the density of the cathode mixture before injecting the electrolyte liquid is 3.2 to 3.5 g/cm<SP>3</SP>, and porosity of the cathode mixture is 10 to 18%. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
