According to the structure, materials composition and development characteristic of the batteries, the recycling importance of waste lithium-ion batteries with LiNixCoyMn1-x-yO2 cathode material is introduced in detail.The preparation and recycling processes of valuable materials,technologies of the patterns of discharging, shredding and the treatment of hazardous substances that produced in shredding are compared comprehensively. The recycling of metal resources (e.g. Cu, Al, Co, Ni, Mn, Li) and organic solvent in electrolyte are analyzed. The key issues and the development prospect of recycling technologies are preliminary discussed.
