PURPOSE:To save time of manufacture and prevent peeling off of a coating film in pouring of an electrolyte at high temperature by coating the end surface of a positive electrode which is exposed in the outside with a low viscosity insulating coating material. CONSTITUTION:The end surface, which is exposed in the outside, of a silver oxide plate 1 is coated with an insulating coating material (such as fluororubber) by using a writing brush to make the coating material penetrate and solidify in pores of the silver oxide plate 1 and to form an insulating film 6. By this process, labor to coat each plate one by one with high viscosity resin by using a spatula is eliminated. Peeling off of resin when high temperature electrolyte (80 deg.C or more) is poured and local cell generation are prevented, and manufacturing time is reduced and reliability of a battery is increased. |
