Research Progress on Resource Recovery Technology of Spent Lithium-ion Batteries
Lithium-ion batteries are one of the effective measures to achieve the carbon peak and carbon neutrality goals,and are widely used in 3C,electric vehicles,energy storage and other fields.After reach-ing the end of the service life,massive spent lithium-ion batteries will be produced,which contain a variety of valuable metal elements and harmful substances,causing a waste of resources,environmental pollution and safety issues if handled improperly.Therefore,the recovery and recycling technology of spent lithium-ion batteries has become the latest research points,and generates global attention.This paper summarizes and reviews the recycling and reutilization technologies mainly from three aspects:disassembly and separa-tion,valuable metal leaching and resource regeneration,and puts forward useful proposals for future devel-opment.
