Abstract

PURPOSE:To suppress a decline of battery voltage derived from water absorption of manganese dioxide by controlling the humidity so that the moisture content of manganese dioxide does not increase during its storage and battery production. CONSTITUTION:Manganese dioxide is stored under a humidity atmosphere so that the moisture content of manganese dioxide does not exceed about 2 percent, by weight, as measured immediately prior to injection of an electrolyte. This manganese dioxide is mixed with graphite powder and the mixture is compressed and formed into a positive electrode composite material 2 and is arranged in a positive electrode case 1. On this positive electrode composite matermial 2, a separator 3, an electrolyte impregnating material 4, a gel negative electrode 5 made of zinc iodide powder containing thickener, and a sealing plate 6 which acts also as a negative electrode terminal are arranged to make up an alkali manganese battery.
