With the rapid development of the new energy industry led by new energy vehicles, a large number of spent power lithium batteries have formed an emerging “urban mineral” with the end of their service life. Therefore, under the background of “dual-carbon”, how to realize the resource recycling of lithium-ion batteries in an efficient, environmentally friendly and low-carbon way has become the difficulty and hot spot of current research. At present, the regeneration methods of cathode and anode electrode materials mainly include direct regeneration (solid phase method, hydrothermal method, molten salt roasting method) and indirect regeneration (co-precipitation method, solgel method), and the advantages and disadvantages of their application in industrial production are summarized. After being repaired and regenerated,the negative electrode materials can be applied to positive and negative electrode materials, catalysts, adsorbents, graphite derivatives and graphite polymer materials, etc., fully demonstrates sustainable recycling of resources. Finally, it analyzes the difficulties and challenges faced by the recycling of used lithium-ion batteries and looks forward to the industrial practice of recycling used lithium-ion batteries, so as to provide feasible references for the realization of lithium-ion battery resource recycling.
