Research Progress on Cathode Material Recycling of Waste Lithium-Ion Batteries
With the increasing large-scale application and production as well as the sales of lithium-ion batteries(LIBs)in electric vehicles,3C electronics and energy storage devices,the metal waste and environmental pollution caused by their retirement are also becoming increasingly prominent.It is necessary to vigorously develop a green,environmentally friendly,efficient and low-cost cathode material recycling process for waste lithium-ion batteries to realize the cycle utiliza-tion of non-ferrous metal resources.This paper reviews the latest progress in the material recycling process of cathode ma-terials for the used lithium-ion batteries.The existing recovery processes are summarized.Moreover,the research status of recovery processes such as the pretreatment,pyrometallurgy,hydrometallurgy,biological leaching and direct recovery strategy are detailed illustrated.The problems and the advantages of these technology are compared and analyzed.Further-more,the recovery efficiency,safety and economic value are comprehensively discussed.Finally,the prospect and development trend of the recycling and reuse of cathode ma-terials of used lithium-ion batteries are outlooked,aiming at the direct,high-value and large-scale research on the recy-cling and reuse of used lithium batteries to provide lessons and references.
