Development of gas phase metallized plaques for electrodes of storage batteries, in particular for nickel oxide electrodes
Abstract
Nickel oxide electrode plaques for alkaline batteries were developed by nickel carbonyl vapor deposition plating on large fiber plaque substrates made of carbon. The most promising technique is the one in which carbonyl gas flows continuously through the carbon felt, allowing continuous processing as well as improved uniformity of the nickel distribution. Structural strength, electrical resistance, heat conduction, and gas permeation of the plaques were approximated by simple models which are borne out by experimental comparison it is indicated that electrochemical measurements in half cell arrangements are reached for nickel savings, capacity per unit area, and current capability.
