Abstract
An integrated preparation method of a long-life hydrogen storage alloy film/Ni foil composite electrode material has been proposed in this paper. The hydrogen storage alloy film/Ni foil composite electrode material was prepared by magnetron sputtering. The prepared film composite electrode effectively reduces the electron/ion diffusion distance, increases the specific surface area of alloy, and reduces the contact resistance between the active material and the current collector. Furthermore, the integrated preparation of long-life hydrogen storage alloy film/Ni foil composite electrode material is realized by depositing method. This paper provides a simple and effective method for reducing the internal resistance and increasing the electrochemical reaction rate of the hydrogen storage alloy, and the prepared film composite could be a promising candidate for Ni-MH batteries.
