The development of new energy vehicles has led to the growth of production and sales of lithium-ion power batteries,among which lithium iron phosphate batteries(LFPBs) have a large market share.Due to the limited lifs of lithium-ion battery,the number of waste LFPBs is increasing year by year.It contains abundant metal resources and also has environmental hazards.Therefore,it has economic and environmental benefits to carry out research on waste LFPBs recovery.Solid phase regeneration is the mainstream scheme of waste LFPBs recovery.The methods of solid phase regeneration for waste LFPBs recovery,such as non-oxidation pretreatment regeneration and oxidation pretreatment regeneration,were summarized.The advantages and disadvantages of each method were compared.The regeneration method without oxidation pretreatment can prepare cathode materials with good crystalline phase.The regeneration method with oxidation pretreatment can control the carbon content of regenerated cathode materials and further improve the discharge capacity of LFPBs.
