A surface-to-bulk tunning deep delithiation strategy towards 5C fast-charging 4.6 V LiCoO2 Achieving highly reversible anionic redox reactions (ARR) in high-voltage LiCoO2 (LCO) is critical for increasing power/energy density but still lacks a reliable tuning strategy.

Ultrathin dense LiF coverage coupled with a near-surface gradient fluorination lattice enables fast-charging long-life 4.6 V LiCoO2 LiCoO2 (LCO) is a leading cathode material of lithium-ion batteries in consumer electronics. However, practical applications of high-voltage fast charging are hampered by unstable interfacial structures and unfavorable phase transitions arising from the superimposed high-flux Li+ diffusion of LCO during deep de-lithiation.
