Abstract
The invention concerns a method of improving the properties of a hydrogen storage alloy powder for a negative electrode of a rechargeable nickel hydride battery. The method comprises the steps of hydriding a powdered alloy starting material, oxidizing the obtained hydride alloy powder and washing the oxidized powder. The invention also concerns the obtained powder.
