Abstract
Nickel-positive electrodes obtained by electrochemical impregnation of aluminum-substituted alpha-nickel hydroxide are found to deliver a reversible discharge capacity of ca. 450 mAh/g. This is much higher than the capacity of beta-nickel hydroxide electrodes [200 mAh/g: this work; 225 mAh/g: Dixit et al., J. Power Sources, 63, 167 (1996)] prepared under identical conditions and pasted electrodes comprising cobalt-doped nickel hydroxide [345 mAh/g: 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 289 mAh/g (le exchange) to 491 mAh/g [1.7e exchange.
