PURPOSE:To obtain a positive-electrode plate with high performance at a low cost by cobalt-plating a porous substrate made of sintered alkali-resistant metal fibers and filling it with an active material made of nickel hydroxide. CONSTITUTION:Alkali-resistant metal fibers obtained by cutting Fe, Ni, etc. are sintered to form a porous substrate. After this porous substrate is cobalt-plated, it is filled with a positive-electrode active material mainly composed of nickel hydroxide, and it is dried and thickness-adjusted to form a paste type positive- electrode plate for alkaline storage battery. Thereby, it can be filled with the active material at a high density, and the utilization factor of the active material can be improved. Accordingly, a positive-electrode plate with a high energy density can be obtained at a low cost. |
