The handling of lithium-ion batteries (LIBs) has emerged as a critical environmental concern as more and more people select electric automobiles and electric cars are seen on the road more regularly. If the spent LIBs are not recovered in time, they will cause serious damage both ecologically and socially harmful. Through recycling, the environmental impact of LIBs can be greatly reduced, and valuable materials can be recovered. In this research, the current situation of LIBs recycling methods, including pyrometallurgy, direct recycling methods and hydrometallurgy are reviewed. Pyrometallurgical recycling is a widely used method which can use little pretreatment. It uses high temperature reaction to reduce the and recover valuable metals. In the hydrometallurgy, chemical leaching of LIBs enables the extraction of several different metals, including lithium, cobalt, manganese, nickel, and aluminum. It is more efficient to refine and separate metals using hydrometallurgy. Direct recycling is a promising approach that recycles valuable metals directly rather than transforming them into raw materials through the application of physical and chemical processes. In conclusion, recycling lithium-ion batteries is a crucial industry that may help address environmental issues and offer a reliable source of valuable resources. The development of LIBs recycling has great prospects and can aid in the sustainable exploitation of resources.
