In this paper, a kind of high power hydrogen storage alloy powder is studied, its components such as main elements of rare earth and nickel as well as auxiliary elements of Co, Mn, Al and Fe are analyzed by inductively coupled plasma (ICP), its texture is analyzed by X-Ray Diffraction (XRD) test and the platform pressure curve is analyzed by reaction with the hydrogen. Moreover, the high power hydrogen storage electrode alloy is developed by carrying out the tests of particle size and specific surface area for hydrogen storage alloy powder as well as analyzing the electrochemical characteristics of alloy electrode. It is determined to meet the requirements of high power and current for Ni-MH battery by constant power test of battery. The charge-discharge performance with high current of Ni-MH battery is realized by optimizing the preparation technology of cathode.
