Direct and green repairing of degraded LiCoO2 for reuse in lithium-ion batteries
文献摘要：
Traditional recycling processes of LiCoO2 rely on destructive decomposition,requiring high-temperature roasting or acid leaching to extract valuable Li and Co,which have significant environmental and economic concerns.Herein,a direct repairing method for degraded LiCoO2 using a LiCl-CH4N2O deep eutectic solvent(DES)was established.The DES is not used to dissolve LiCoO2 but directly serves as a carrier for the selective replenishment of lithium and cobalt.Replenishment of lithium restores LiCoO2 at different states of charge to a capacity of 130 mAh/g(at 0.1 C rate),while replenishing the cobalt increases the capacity retention rate of 90％after 100 cycles,which is comparable to pristine LiCoO2.The DES is collected and reused multiple times with a high repair efficiency.This process reduces energy consumption by 37.1％and greenhouse gas emissions by 34.8％compared with the current production process of LiCoO2,demonstrating excellent environmental and economic viability.
