An investigation into the effects of adding cobalt hydroxide to nickel hydroxide electrodes has provided some insight as to why cobalt is an effective additive. The investigative techniques emphasized in situ measurements of electrode mechanical behavior rather than electrochemical data as employed previously. It is found that electrode growth markedly reduced by the addition of cobalt and conclude that increasing the amount of cobalt hydroxide in the nickel hydroxide active material results in an active material deposit of decreased mechanical rigidity. Decreasing rigidity results in less mechanical strain of the nickel sinter and thus a reduced rate of nickel electrode capacity loss due to mechanical fatigue. 9 refs.
