Abstract
Commercial alkaline accumulators with positive electrode based on nickel hydroxide generally comprise beta modification of the active material at present due to its excellent stabilization of performance during electrochemical cycling. The paper refers to a part of research work accomplished in R&D Department of the company Bochemie Inc., which has been aimed to utilization of alpha nickel hydroxide in alkaline batteries including exploration of possibilities to attain its stability in strong alkali medium of the electrolyte. We have focused our effort to elucidate reasons for its transformation tendency and to find way of their suppression. Based on previously obtained empirical evidence, introduction of appropriate variations in depth of discharge seems to be potentially proper solution for us, which led us to verify that.
