Abstract： The production of lithium-iron phosphate batteries increases with the promotion of new energy vehicles year by year, and the corresponding spent lithium-iron phosphate batteries are also produced in large quantities. If not dealt with in time, it will cause environmental pollution and resource waste. In this paper, the research progress on resource reuse of spent lithium-iron phosphate material in recent years, including separation of spent lithium-iron phosphate materials and current collection, and reuse of spent lithium-iron phosphate materials, which consists of selective extraction of elements, the regeneration etc., then their advantages and disadvantages are summarized, and finally the recycling development direction of the spent lithium-iron phosphate material in the future is prospected.

Keywords： spent lithium-iron phosphate recovery separation selective extraction regeneration
