A manganese-lithium separation process and a pre-extraction solution preparation process in comprehensive recovery of ternary battery wastes, and a method for comprehensive recovery of cobalt, nickel, manganese and lithium elements from the ternary battery wastes, relates to a method for recycling battery wastes. According to the present disclosure, cobalt and nickel ions are separated from an impurity-removed solution by a hydrolysis method; manganese, lithium and other ions in the impurity-removed solution are free from an extraction procedure, so that most manganese ions are separated and removed by a wet method before extraction, to prevent the manganese ions from entering the extraction system; nickel ions are free from an extraction procedure of full extraction and full back-extraction; and nickel hydroxide is directly precipitated after related impurities are removed by extraction.

A method for disassembling and separating a waste lithium-ion battery comprises: directly tearing a battery pack or a cell of the waste lithium-ion battery with water and electricity without discharging after removing a housing, then performing first wet screening, directly performing wet degumming without drying after recovering an electrolyte and removing iron by magnetic separation, then performing first crushing with water, third wet screening and second crushing with water after performing second wet screening, and finally performing jigging separation to obtain copper powder, aluminum powder, positive and negative electrode materials, plastic powder and separator pulp.
