Abstract
Double hydroxides of the formula, Ni1-xZn2x (OH)2 (CO3)x· nH2O (x = 0.1 to 0.25) having the same structure as that of α-nickel hydroxide have been synthesized by partial substitution of zinc for nickel. The hydroxide having the composition x = 0.25 exhibits prolonged stability in 6 M KOH. Pasted electrodes comprising this material are rechargeable with a stabilized reversible discharge capacity of 410 ± 15 mAh g-1 of nickel even under suboptimal conditions of electrode fabrication. This compares favorably with the capacity values achieved for β-nickel hydroxide (221 mAh g-1. This work; 297 mAh g-1, Delahaye-Vidal and Figlarz; 456 mAh g-1, theoretical).
