PURPOSE:To increase the capacity of a battery by using carbon hydroxide having plate-like particle in a nonsintered nickel electrode in which cobalt hydroxide is added to nickel hydroxide to increase the utilization of active material. CONSTITUTION:Nickel hydroxide and cobalt hydroxide having a plate-like particle are mixed in a ratio of 92.5:7.5 by weight. Water and a thickening agent are added to the mixture to form paste, and the paste is filled in a porous sintered nickel fiber substrate. The filling ratio of the active material is 1.63g/cc void, and the press pressure required to increase to 2.40g/cc void is 290 kg/cm<2>. The filling ratio of the active material to the porous substrate is increased and the capacity of a battery is increased. The press pressure after filling the active material can be reduced and the productivity is increased. |
