PURPOSE:To keep down the oxidative deterioration in a separator, by forming the silver oxide into a structure being coated with manganese dioxide more feeble in the force of oxidization. CONSTITUTION:A negative pole terminal plate 6 serving as a negative pole collector body charged with a negative pole agent 2 inside a fitted into the opening part of a positive pole can 5 seen likely nickel-plating an iron provided with positive pole black mixture 1, a separator 4 and an electrolyte absorbent 3 via various resins including nylon, polyethylene, polypropylene, etc., or a section L-shaped ring gasket 7 of rubber make, and the inner part of a cell is rendered airtight in structure by fastening the positive pole can 5 inward. The above-mentioned positive pole black mixture 1 is made up in the following process that silver oxide powder is granulated into 100-300mum or so in advance, then a manganese dioxide of about 2-20mum is mixed with this granulated silver oxide and, at the time of this mixing, each surface of the said silver oxide granule is layered by dint of the moisture absorption and water absorbability of the manganese dioxide. This black mixture is press-molded into the specified thickness by means of a routine process. The amount of the said manganese dioxide used is set at 2-7pts.wt. to 100pts.wt. of the silver oxide. |
