Title: Alkaline-zinc storage battery
Inventor: FURUKAWA SANEHIRO
IPC: H01M4/24
Filed: 1985-11-08
Abstract: PURPOSE:To prevent the high density deposition of zinc in the vicinity of the zinc electrode surface and the exfoliation and falling off the active material from the collector by adding metalic zinc powder only to the active material layer located on the zinc electrode surface. CONSTITUTION:In a battery provided with the zinc electrode made by forming the active material layer on the collector surface, the active material layer is constructed with two layers, the inner layer contacted to the collector surface and the surface layer located on the zinc electrode surface, and metallic zinc powder is added only to the surface layer. As the metallic zinc is not contained in the inner layer of the zinc electrode, even when the metallic zinc of the surface layer is self-discharged the flow of electrons between the surface layer and the collector is suppressed because of the existence of the low electro-conductive inner layer between the surface layer and the collector. Thereby the generation of the hydrogen gas at the collector surface can be suppressed to prevent the deterioration of the adhesiveness between the collector and the active material layer. And for the sake of the low electric conductivity of the inner layer, the charging reaction in the charging process is initiated in the vicinity of the collector, and the concentration of the reaction in the surface layer can be suppressed to deepen the reaction zone so as to relax the high density reaction on the surface.
