Investigates lithium extraction effects on layered oxide cathode performance, suggesting improved structural reversibility.
during charging. Consequently, we observe the suppressed formation of aggregated vacancies and O-O dimers within the TM layers. Ultimately, our synthesized O2/O6 Li-excess demonstrates enhanced structural reversibility and improved capacity/voltage retention. This oxygen-stacking engineering provides a compelling strategy for developing cathodes with enhanced local structural reversibility.
