With the rapid development of the new energy vehicle industry and the energy storage field, the comprehensive recycling of a large number of spent LiFePO4 batteries has become a key challenge and urgent demand for the sustainable development of new energy in China. This paper summarizes the principle, advantages and disadvantages, research and application status of major strong dissociation technologies for retired LiFePO4 battery cathode materials, including pyrometallurgy, hydrometallurgy, mechanochemistry, electrochemical metallurgy, etc., and further expounds the innovation progress of strong dissociation technology in improving the recovery efficiency of valuable components, reducing costs and reducing environmental impact. The future development trend is also prospected.
