With the popularization of intelligent terminals and the coming of “5G era”, the quantity of used LiCoO₂ batteries has been increasing year by year. Due to its rich Co content, used LiCoO₂ battery is an important source to ease the tight supply of Co in China. Thus, its recycle is of great practical significance. In this paper, the status quo of study on the recycle of used LiCoO₂ batteries is introduced, and the recycling methods are analyzed from the respects of advantages and disadvantages. These methods mainly include pyrogenic process, wet process, material regeneration, etc. Moreover, the research and development trends of recycling used LiCoO₂ batteries are discussed.
