Abstract

The diffusion coefficients of protons moving in the Ni(OH)2 electrodes have being investigated by constant current,cyclic voltammetry and potential step technineques.The electrodes were prepared by cathodic deposition and their active material contained 0~53% cobalt.It was found that the diffusion coefficients are about 10(-9)~10(-10) cm2/s during charging and about 10(-11) cm2/s during discharging.Moreover the value increases with the increacing content of Co in the electrodes.During the calculation,the relevant fomulars were modified especially the wrong fomular for constant current methode.
