Abstract

Nickel‐positive electrodes obtained by electrochemical impregnation of aluminum‐substituted hydroxide are found to deliver a reversible discharge capacity of . This is much higher than the capacity of hydroxide electrodes [ : this work; : Dixit et al., J. Power Sources, 63, 167 (1996)] prepared under identical conditions and pasted electrodes comprising cobalt‐doped nickel hydroxide [ : Faure et al., J. Power Sources, 36, 497 (1991)]. These observations suggest that the theoretical target‐capacity for high‐performance nickel‐positive electrodes must be revised from the currently accepted value of (1e exchange) to [ exchange: Corrigan and Knight, J.
