Simultaneous Regulating the Surface, Interface, and Bulk via Phosphating Modification for High‐Performance Li‐Rich Layered Oxides Cathodes

Li-rich Mn-based layered oxides (LRMOs) are regarded as the leading cathode materials to overcome the bottleneck of higher energy density. Nevertheless, they encounter significant challenges, including voltage decay, poor cycle stability, and inferior rate performance, primarily due to irreversible oxygen release, transition metal dissolution, and sluggish transport kinetics. Moreover, traditionally single modification strategies do not adequately address these issues. Herein, an innovative "all-in-one" modification strategy is developed, simultaneously regulating the surface, interface, and bulk via an in-situ gas-solid interface phosphating reaction to create P-doped Li
