💡 Novelty & Significance:
The novelty lies in a synergistic strategy combining oxygen vacancies, spinel phase, and TiF₄ coating to stabilize localized O₂ⁿ⁻ in Li-rich cathodes. This interface reconstruction suppresses oxygen release and side reactions while enabling 3D Li⁺ diffusion. Significance: exceptional cycling stability (96% retention after 200 cycles at 2C/5C) and near-zero decay over 300 cycles at 1C, advancing practical Li-rich cathode applications.
