Abstract
The nickel electrodes in Ni-Cd pocket-plate batteries have been cobalt-dope d (0.8-5.0 wt.%) either by coprecipitation during Ni(OH)(2) fabrication or by addition of cobalt oxide. It was observed that both methods of doping si gnificantly improved the initial performance and performance after accelera ted testing. In general, the higher the cobalt content, the higher the degr ee of material utilisation. (C) 2000 Elsevier Science S.A. All rights reser ved.
