On the elemental substitutions of titanium-based hydrogen-storage alloy electrodes for rechargeable Ni-MH batteries

Journal Article


Abstract


  • Partial substitutions of nickel in Ti2Ni intermetallic compound with cobalt, potassium, boron and aluminium have been studied in the present paper. It is found that cobalt and boron additions are beneficial but aluminium addition is detrimental to the specific capacity of the electrode. Potassium does not have any significant effect on the specific capacity of the electrode from our work. Cobalt, potassium and aluminium additions are all found effective in increasing the cycle life of Ti2Ni electrode, although by different mechanisms.
