英文摘要	This paper aims to explore the possibility of using spent carbon anode residue (SCA) from aluminum electrolysis as anode materials for lithium-ion batteries. SCA of hazardous solid waste is recovered by a two-stage process of "chemical leaching–high-temperature graphitization" to achieve harmlessness and resource treatment. Chemical leaching can increase the carbon purity of SCA-CL from 61.86% to 92.80% and cause the formation of surface holes-defects structure, which serves to shorten the Li+ transmission distance. High-temperature graphitization can increase the carbon purity of SCACL2800 to 99.90% and cause the significant graphite sheet structure, which can increase the conductivity. SCA-CL-2800, used as the anode material for Li-ion batteries, showed the first capacity of 359.1 mAh g−1 at 0.1 C, the initial coulombic efficiencies of 80.17% and a reversible capacity of 368.6 mAh g−1 after 50 cycles. Compared with graphite, SCA-CL-2800 exhibited excellent electrochemical performance. It is estimated that the preparation method provides an innovative strategy for recovery and application of similar solid waste. © 2021
