Abstract : The impedance of porous nickel electrodes has been measured under conditions of steady-state oxygen evolution. Significant effects are observed due to the pore structure of the electrodes, and these effects are found to correlate with loading levels, performance, and composition. The oxygen evolution characteristics of sintered plate electrodes have been investigated as a convenient means for determining the structural uniformity and the overall quality of such plates for use as battery electrodes. Keywords: Nickel electrodes, Nickel hydroxides, Tafel slopes, Sintered electrodes.
