Abstract
This invention relates to a hydrogen storage alloy electrode prepared from an active material comprising a magnesium based alloy and a Ni, P based metallic compound. The magnesium based alloy is coated while in powder form with a Ni, P based metallic compound and activated by heat. The hydrogen storage alloy electrode produced from this active material is able to absorb and desorb hydrogen even under normal temperature and pressure. The alkali battery assembled with the electrode prepared from the activated alloy material has high energy density and charge-discharge capacity and can be used in large scale electrical equipment, especially electrically operated vehicles.
