Constructing Face‐Shared Configuration at the Hetero‐Interface in Li‐Rich Layered Oxide Cathodes

deintercalation/re-intercalation reversibility. Benefiting from the introduction of the non-Li-rich O2 phase, the heterostructure improves the structural stability of the conventional O3 phase, yielding superior capacity/voltage retention. By elucidating the interaction mechanism at the heterointerface, this structural design provides a compelling strategy for developing practical Li-rich cathodes with high capacity and enhanced structural stability.
