摘要

LiNi_0.8Co_0.1Mn_0.1O₂ cathode material was re-synthesized from discard LiCoO₂ batteries by pre-treatment, acid leaching and co-precipitation. The concentration of metal ion in leachate was analyzed by ICP-OES, the morphology and structure of cathode materials were characterized by the SEM and XRD, and the electrochemical properties of coin batteries were performed by the electrochemical tests. The results show that the regenerated material (R-NCM) from acid leaching lixivium exhibits the desired morphology and well layer structure. Under the condition of 2.8~4.3V, the initial discharge capacity of R-NCM is 210.8 mAh/g at 0.2C. After 50 cycles, the discharge capacity and capacity retention of re-synthesized cathode material are 183 mAh/g, 87%, respectively, showing good cycle performance, providing support and development direction for the regeneration of used lithium-ion batteries.
