Abstract
Significant difference between the working capacities in zincate electrolytes of reversible nickel oxide electrodes of two types, lamellar with a graphite additive and metal-ceramic, was noted. It was demonstrated that the electrochemical reversibility of the active substance of nickel oxide electrodes is strongly impaired in the simultaneous presence of the carbon (graphite) component and oxygen in the reacting electrodes and zincate in the electrolyte. In operation of electrodes of this kind in alkaline nickel-zinc batteries, the oxygen-involving process is of side (parallel) nature.
