The invention discloses a method for leaching and recovering metal from lithium ion battery anode wastes based on an electrochemical method. The method comprises the steps of compacting lithium ionanode waste powder into a flake shape as a negative electrode, adopting an inert electrode as a counter electrode, adopting a solution containing H<+>, K<+> and/or Na<+> as an electrolyte solution, and carrying out electrochemical reduction leaching under direct voltage to obtain an electrolyte solution containing metal ions. Compared with traditional acid leaching (acid plus a reducing agent), according to the method, the acid dosage is greatly reduced, the leaching time is short, the operation can be carried out at normal temperature, the leaching efficiency of metal in a manganese-nickel-cobalt ternary cathode material is greatly improved, the method is simple to operate, and wide in industrial prospect, and the cost is low.
