Reinforcing Particle Architectural Stability of Li-Rich Cathode With Enhanced Anionic Redox Reaction Reversibility.

ABSTRACT: Lithium-rich layered oxides (LRLOs) promise exceptional energy densities (∼1000 Wh kg^-1) but suffer from coupled structural and chemical instabilities that impede their commercialization. While atomic scale regulation of anionic redox reaction (ARR) reversibility has been extensively explored, the mesoscale architectural degradation, which is exacerbated by detrimental porous structures inherited from precursors, remains critical yet overlooked. Herein, a cross-scale synergistic strategy was introduced to simultaneously reinforce the mesoscale particle architecture and stabilize the atomic-scale charge compensation in LRLOs. By incorporating fluorine to modulate the local electronic environment, the surface energy of the active (010) facets is selectively lowered, driving a prof
