Intensification of Nickel Hydroxide Properties in Order to Improvement of Its Electrochemical Behavior in Alkaline Accumulators
 Máca, Tomáš ; Vanýsek,, Petr (referee) ; Studničková, Marie (referee) ; Sedlaříková, Marie (advisor)
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. This dissertation refers to a research work accomplished by author, 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. I have focused my effort to elucidate reasons for its transformation tendency and to find way of their suppression.
