[0002] As the negative electrode material of nickel-hydrogen batteries, the performance of hydrogen storage alloy powder directly affects the performance of the battery. The product quality of hydrogen storage alloy powder is determined by the correct process route, and the control of process sampling and sample preparation is also particularly important. Due to the particularity of metal powder alloys, hydrogen storage alloys can usually only be crushed in an oxygen-free environment and ground in an orderly manner in a traditional pounding pestle to prevent the ground alloy from heating and burning.
