WebHerein, we conduct systematic investigations into the failure mechanisms of LiCoO 2 upon high voltage cycling and reveal that the capacity loss is mainly due to bulk structure degradation and the voltage fading is mainly due to the blocking effect of the cathode/electrolyte interphase (CEI) layer. WebEnhancing the high voltage cycling stability is critical for reviving LiCoO2-based layered cathodes, and this requires in-depth understanding of various degradation mechanisms and their contributions to performance decay. Herein, we conduct systematic investigations into the failure mechanisms of LiCoO2 upon
