/ 2 Metal Hydride Cathode for Ni/MH Secondary battery Using Zircaloy scrap

摘要

In order to reduce the price of the hydrogen storage alloy which is a negative electrode active material for Ni / MH secondary batteries, a low-priced zirconium alloy scrap (Zrcaloy scrap, Zr-s) is used instead of zirconium (Zr), which is a high cost ratio element among hydrogen storage alloy elements. It relates to a hydrogen storage alloy for Ni / MH secondary battery using the).;The present invention is processed at low cost without changing the thermodynamic and electrochemical properties of hydrogen storage alloy using pure zirconium by processing a zirconium alloy (Zircaloy) used in nuclear reactors (Zircaloy) into a zirconium alloy scrap (Zircaloy scrap) and replacing it instead of pure zirconium. To provide a Zr-based hydrogen storage alloy.
