Electrodepositing nickel over alkaline cell electrodes

摘要

Manufacture or treatment of alkaline cell electrodes or plates (especially negative electrodes) in which the electrodes whether in the charged or discharged state are subject to an electro-deposition of nickel over the exterior surface area of the electrodes. The electrodes are preferably subject to a high current density for short duration nickel plating ("flash nickel" plating). The treatment has particular practical application to sintered nickel electrodes impregnated with cadmium hydroxide, i.e. for sealed nickel cadmium cells as well as to sintered zinc electrodes. The invention includes electrodes when so manufactured or treated and also cells or batteries containing them.
