Abstract:

To meet the needs of sustainable energy and green development, the lithium-ion battery (LIB) market has continued to proliferate recently. However, limited by a certain life, the number of spent LIBs will also be produced. Spent LIBs will lead to resource waste and severe environmental pollution, so the recycling of spent LIBs is an inevitable key issue. Graphite is an ideal anode material and occupies a dominant position in the LIBs market due to the advantage of low cost, abundant reserves, high energy density, and long cycle life. Currently, the research on battery recycling mainly focuses on the metals in cathode material, but the recycling of anode material must be addressed. This review briefly discusses the status of LIB recycling and emphasizes the necessity of anode graphite recycling. The main failure mechanism on anode material, the effects and changes on the anode graphite material, and the characteristics of spent anode graphite were summarized. Then the research progress on the recycling of anode graphite was reviewed, including regeneration, modification, and reutilization. The recycling challenged were identified, and the prospects for the recovery and reuse technology were put forward to promote the sustainable development of the battery industry.

Key words: spent lithium ions batteries, anode graphite, recovery, reutilization
