Porous plaques that contain hollow nickel fibres are successfully prepared by a traditional slurry-scraping technology. The fibrous, nickelplaque materials have high porosity (85-87%) and are for application in high specific-energy nickel-metal hydride batteries. Nickel electrodes are fabricated by

New hydrated cobalt-substituted nickel hydroxides were prepared and characterized. These materials were obtained either by precipitation (a) or by the "chimie douce" technique (a\* and a'). Cobalt generally stays in the trivalent state. In contrast with the aco~+ phases, the aco,\* phases are stable
The performance and structural characterlstrcs of PTFE bonded nickel hydroxide electrodes have been studied as a function of electrolyte composition, temperature, and overcharge. The results demonstrate that crystal growth and the relative stability of the &NiOOH and y-NiOOH oxrdlsed phases are hig
