Title: Zinc-substituted {alpha}-nickel hydroxide as an electrode material for alkaline secondary cells

Abstract

Double hydroxides of the formula Ni{sub 1{minus}x}Zn{sub 2x} (OH){sub 2}(CO{sub 3}){sub x}{center_dot}nH{sub 2}O (x = 0.1 to 0.25) having the same structure as that of {alpha}-nickel hydroxide have been synthesized by partial substitution of zinc for nickel. The hydroxide having the composition x = 0.25 exhibited prolonged stability in 6 M KOH. Pasted electrodes comprising this material are rechargeable with a stabilized reversible discharge capacity of 410 {+-} 15 mAh/g of nickel even under suboptimal conditions of electrode fabrication. This compares favorably with the capacity values achieved for {beta}-nickel hydroxide (221 mAh/g, this work; 297 mAh/g, Delahaye-Vidal and Figlarz; 456 mAh/g, theoretical).
