摘要：
The direct regeneration is the most ideal way for recycling of retired lithium-ion batteries' cathode materials, because of its low cost, low energy consumption, and low emissions, which highly meets the demand of low carbon development in China. The recent research progress of the direct regeneration was comprehensively reviewed. Firstly, the pretreatment methods of alkaline solution, organic solvents soak, and heat treatment etc. were presented and their respective effect and influence were introduced. Secondly, the researches of direct regenerating retired lithium cobalt oxides, lithium nickel cobalt manganese oxide, lithium manganate, and lithium iron phosphate were summarized, respectively. The regeneration methods of roasting, hydrothermal, electrochemical, and chemical re-lithiation were reviewed, and their respective features, advantages and shortcomings were analyzed. Finally, the possible application challenges of the direct regeneration recycling were analyzed from multiple perspectives, and suggestions were made. © 2023 Central South University of Technology.
