PURPOSE:To obtain high voltage and large discharge current and thereby to improve repetitive charge-discharge cycle characteristics by constituting the positive pole with material of its main constituent of manganese dioxide. CONSTITUTION:Mixture of titanium and nickel is resolved and hydrided, the alloy hydride is pulverized in argon atmosphere. The pulverized powder, PTFE (polytetrafluoroethylene) powder and acetylene black are mixed up, the mixture to which solid electrolyte is moreover added is formed into pellet and employed as the negative pole 1. Meanwhile, antimony pentaoxide transformed from antimony pentachloride is pelletized and employed as a solid electrolyte 2. Electrolytic manganese, acetylene black and the solid electrolyte are mixed up and pelletized, and employed as the positive pole 3. With this constitution, high voltage and large discharge current is obtained, and moreover, cycle characteristics are improved for repetitive charge-discharge. |
