PROBLEM TO BE SOLVED: To provide an anode material having high capacity and capable of charge and discharge at high rate, and the method thereof. SOLUTION: The anode material for a nonaqueous electrolyte secondary battery is formed by applying alloy electrolyteless plating on a copper foil as an anode substrate. The directly alloy electrolyteless plating is selected from Sn-Ni, Zn-Ni, and Sn-Co. In the manufacturing method of the anode material, reducing agent for plating is to be a boron hydride compound or a hypophosphite compound so that B or P is included. Furthermore, plating having different compositions in the interior layer and the exterior layer of a copper foil is performed. In the manufacturing method, by heat treatment of the plate coat according to necessity, the plate can be an intermetallic compound. |
