| 摘 要： | The Ni(OH)2 film electrodes doped respectively with alkali-earth metals aluminum, lead, partial transi-tion metal and some rare-earth metal (altogether 17 kinds of metals) ions were prepared by cathode electrode-position. The electrode reaction reversibility, the difficult extent of oxygen evolution, the proton diffusion coefficient, the discharge potential of middle value and the active material utilization of the Ni(OH)2 film elec-trode were compared with those of the ones doped with the metal ions by means of cyclic voltammetry, poten-tial step and constant current charge-discharge experiments. It was found that Ca^2 , Co^2 , Cd^2 , Al^3 etc. have obviously nositive effect.

| Abstract: | The Ni(OH) 2 film electrodes doped respectively with alkali-earth metal aluminum, lead, partial transition metal and some rare-earth metal(altogether 17 kinds of metals) ions were prepared by cathode electrodeposition. The electrode reaction reversibility, the difficult extent of oxygen evolution, the proton diffusion coefficient, the discharge potential of middle value and the active material utilization of the Ni(OH) 2 film electrode were compared with those of the ones doped with the metal ions by means of cyclic voltammetry, potential step and constant current charge-discharge experiments. It was found that Ca 2+ , Co 2+ , Cd 2+ , Al 3+ etc. have obviously positive effect. |
