Figure 15. (A) Method for electrochemically inserting Li+ into LixCoO2 electrodes from the spent LIBs, thus generating new LiCoO2 materials. (B) The proposed mechanism for directly regenerating LiCoO2 materials through the electrochemical insertion of Li+ ion into the LixCoO2 electrode. Cycling performance of the Li/LiCoO2 electrode from (C) the regenerated LiCoO2 electrode and (D) commercial LiCoO2 electrode at C/5 current rate.
