Title: Negative plate for alkaline battery
Inventor: YOSHIMURA MASAYUKI
IPC: H01M4/62
Filed: 1984-06-27
Abstract: PURPOSE:To obtain a negative plate for non-sintered type alkaline storage battery having good mechanical strength and high active material utilization by using vinyl acetate resin as at least one of binders. CONSTITUTION:In a manufacturing process of a paste type cadmium negative plate, vinyl acetate resin keeps mechanical strength of the plate until it is fed to a formation process. In the formation process, vinyl acetate resin reacts with electrolyte to be converted into polyvinyl alcohol and dissolves in electrolyte, but mechanical strength of the plate is maintained by a network of metallic cadmium produced in the plate. When a formation process is applied in the manufacturing process, mechanical strength of the plate is maintained by vinyl acetate resin until a battery is assembled. After assembling, mechanical strength is kept by mutual compression of plates. Since vinyl acetate resin is finally converted into polyvinyl alcohol which dissolves in electrolyte, contact area of active material with electrolyte and porosity of the plate are increased. Therefore, active material utilization, high rate charge-discharge performance, and gas absorption ability are increased.
