Abstract
The effects of the composition of the electrode surface in contact with the electrolyte on the ability of an air cathode to withstand the rigours of oxygen evolution during charging have been investigated. Of the composition studied, a sintered nickel surface containing silver, mercury and PTFE exhibited the lowest oxygen evolution potential. With a cycle regime consisting of 1 h oxygen reduction at 26 mA/square cm followed by 2 h oxygen evolution at the same current density, the oxygen reduction potential decreased by 156 mV during 41 cycles.
