Method for recycling positive electrode material of lithium ion battery by using amino acid type eutectic solvent

The invention discloses a method for recovering a lithium ion battery positive electrode material by using an amino acid type eutectic solvent, belongs to the field of solid waste recovery, and solves the problems of high price, difficult recovery and high recovery cost of lithium cobalt oxide in the prior art. According to the technical scheme, the method comprises the following steps: taking an amino acid type eutectic solvent as a solvent, and recycling lithium cobalt oxide in the positive electrode material of the lithium ion battery; the hydrogen bond acceptor of the deep-eutectic solvent is valine, and the hydrogen bond donor of the deep-eutectic solvent is lactic acid; and the structure of the valine of the hydrogen bond receptor is # imgabs 0 #, and the structure of the lactic acid of the hydrogen bond donor is # imgabs 1 #. The method has the advantages that the defects in the prior art can be overcome, the conditions are mild, the method is green and efficient, the cost is low, the atom utilization
