Abstract
A method for preparing a copper-based anode material from a waste battery includes the following steps: (1) disassembling a waste battery and taking out an anode plate; (2) using the anode plate in step (1) as an anode and taking a copper foil current collector as a cathode, and placing the anode and the cathode in an electroplating solution for electroplating; (3) after the electroplating is completed, collecting anode powder separated from the anode and soaking the copper foil current collector in an acid solution; (4) washing and drying the soaked copper foil current collector; and (5) calcinating the copper foil current collector to obtain a copper-base anode material.
