Progress in Hydrometallurgical Recovery Process for Spent Lithium-Ion Batteries
Spent lithium-ion batteries contain a large amount of valuable metals such as cobalt,nickel,and lithium,and have a very high recycling value.In this paper,the hydrometallurgical recovery process of spent lithium-ion batteries is reviewed,including pretreatment,valuable metal leaching,and valuable metal separation and purification,and finally the hydrometallurgical recovery of spent lithium-ion batteries is prospected.
