Abstract
Potentiodynamic cycling is proposed to select conditions for the activation of zirconium-alloy electrodes of a nickel-hydride accumulator. The electrochemical characteristics of the electrodes are studied. It is shown that the full charge and discharge capacities are impossible in hydrogenation-dehydrogenation conditions that do not correspond to the polarization curves. The maximum discharge capacity under the same conditions is achieved for an electrode of 0.5 g while incomplete discharge capacity is observed for a sample of 0.1 g.
