Abstract

Ageing of the manganese substituted nickel hydroxides in 5M-KOH electrolytic medium leadsto a structure interstratification which is related to spontaneous oxidation of trivalentmanganese ions to the tetravalent state, As far as the electrochemical behavior is concerned, the trend to interstratification has a positive influence on the stability of the capacity upon cycling. In addition, the chargeability is improved by the presence of manganese.
