摘要: This invention relates to a non-aqueous electrolyte cell having an improved utilization of manganese dioxide. The utilization of manganese dioxide of a conventional non-aqueous electrolyte cell comprising a negative active material which comprises lithium, sodium or the like; a positive active material which comprises manganese dioxide; and a non-aqueous electrolyte can be greatly improved by limiting the particle sizes of manganese dioxide powder, carbon powder and optional binder powder contained in the positive mass to, respectively, up to 30 .mu.m, up to 5 .mu.m and up to 3 .mu.m.

摘要: A positive plate composite agent consisting of a mixture of manganese dioxide, carbon powder and polytetrafluoroethylene powder is press-molded at a pressure in the range of 1 to 5 t/cm.sup.2. The resulting molded article is then pulvertized into massive particles having a particle size ranging from 0.03 to 15 mm.sup.3. The massive particles are then press-molded into a positive plate having a predetermined shape at a pressure in the range of 0.2 to 1 t/cm.sup.2.There is thus obtained a positive plate of an enclosed type battery which comprises a portion consisting of the compactly formed massive particles of the positive plate composite agent and a portion consisting of the coarsely formed small particles of the composite agent interposed between the massive particles so as to define paths or voids for the passage of an electrolyte.
