Abstract
The hydrometallurgical process for recycling ternary cathode material of spent Li-ion battery was reviewed.The recycling technologies were divided into three steps of pretreatment,leaching of cathode material,separation and recycle of different elements.The active substances were separated from other cathode materials such as aluminum foil by the pretreatment process,including alkali leaching,organic solvent dissolution and pyrolysis.The solid wastes were converted into recyclable ionic solution by the leaching process,including inorganic acid leaching,organic acid leaching and biological leaching.Lithium,cobalt,manganese and nickel were separated and recycled by separating and recovering process,including chemical precipitation,solvent extraction,electrodeposition,salting out,ion exchange and so on.The progress in the re-synthesis of the new battery cathode material by using the waste ternary cathode material was introduced.关键词
