Figure 15. (A) Method for electrochemically inserting Li⁺ into Li_xCoO₂ 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 Li_xCoO₂ electrode. Cycling performance of the Li/LiCoO₂ electrode from (C) the regenerated LiCoO₂ electrode and (D) commercial LiCoO₂ electrode at C/5 current rate.
