The invention discloses a recovery method for waste lithium ion battery anode materials based on a mechano-chemical method, and belongs to the field of waste lithium ion battery recycling. The waste lithium ion battery anode materials are ground into powder, the powder is sufficiently and evenly mixed with an activating agent and an organic reducing agent, the activating agent can generate activefree radicals, a mixture is obtained, the mixture is subjected to ball grinding, the waste lithium ion battery anode materials generate plastic deformation, lattice imperfection is generated in crystal particles, and the crystal particles generate crystal transfer or are not crystallized; and products obtained after ball grinding are added into deionized water, and valuable metal ions are leached.The method does not depend on high-concentration strong acid, strong base, strong oxidization reducing reagents, expensive organic acid and the like, the mechano-chemical reaction in a solid phase isadopted as a reaction body, and efficient leaching of valuable metal lithium, cobalt, nickel, manganese and the like in the waste lithium ion battery anode materials is achieved under the mild leaching environment.
