With the continuous and further development of new energy vehicles and energy storage industry, the quantity of used lithium ion batteries has been increasing by years. The recycle of used LiFePO 4 batteries has multiple benefits and thus becomes a research hotspot. In this paper, the research progress of recycling used LiFePO 4 batteries in recent years is introduced; the regeneration and recycling methods are especially analyzed, mainly including direct regeneration and wet process for recovering Li and so on; the advantages and disadvantages of each technical solution are analyzed; and the major developmental direction of recycling used LiFePO 4 batteries is expected.
