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

Polarization curves for the anodic oxidation and cathodic reduction of Ni(OH), electrodes at constant current have been obtained, and also Tafel curves for the anodic process. A comparison is made between the electrochemical behaviour of freshly prepared and of recrystallized Ni(OH)2 layers, and the
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
