A Novel Bifunctional Self‐Stabilized Strategy Enabling 4.6 V LiCoO2 with Excellent Long‐Term Cyclability and High‐Rate Capability

Abstract Although the theoretical specific capacity of LiCoO2 is as high as 274 mAh g−1, the superior electrochemical performances of LiCoO2 can be barely achieved due to the issues of severe structure destruction and LiCoO2/electrolyte interface side reactions when the upper cutoff voltage exceeds...
