Abstract

PURPOSE:To stabilize the output voltage of an alkaline battery and to improve its liquid leakage proofness, by using as an active material for the positive electrode of the battery gamma-MnO2 whose pH value is controlled within a specific range. CONSTITUTION:In a positive electrode can 1, are enclosed a positive electrode compound 2, separator 4, electrolyte-impregnated material 5, and negative zinc electrode 6. The can 1 is hermetically sealed by a sealing plate 7 with a packing 8 interposed therebetween, thereby forming a button-shaped battery. The positive electrode compound 2 of such a battery is made of a mixture of gamma-MnO2 and graphite powder. As the gamma-MnO2, is used that having a pH value in the range of 7.5-9.5. This pH adjustment is conducted by treating gamma-MnO2 with an aqueous solution of caustic potassium. It is preferable to adjust the particle size of gamma-MnO2 within a range of 0.3-250mum. In the above constitution, it is possible to reduce the corrosion of zinc and to improve the stability of the output voltage and liquid leakage proofness of the battery.
