Abstract
A novel method for forming powder of a hydrogen storage alloy without the need for further mechanical processing. The alloy powder may be adapted for use as the negative electrode material of rechargeable electrochemical, hydrogen storage cells. The method includes the step of controlling the hydrogen concentration within the hydrogen storage alloy to form powder where 90% of the particles are less than 250 microns in average dimension.
