N2 - The electrode resistance of metal hydride in constant-current electrolysis is investigated. It is found that the diffusion of hydrogen in the electrode is the rate-determining step in the reaction and is the dominant cause of the electrode resistance. The activity of the electrode, corresponding to the reaction rate, is determined by the effective surface area and the diffusion coefficient of hydrogen in the bulk of the electrode. Some parameters concerning the electrode kinetics are estimated. TiMn1.5is an excellent electrode material for a secondary battery with high current and energy densities.
