Nevertheless, their practical application is severely limited by two unresolved challenges: structural degradation from uncontrolled Li/Ni mixing and interfacial instability exacerbated by air/electrolyte corrosion. Herein, we propose a dual-modulation strategy to synthesize a stable Ni-rich cathode via carboxylate-based metal–organic frameworks (MOFs)-derived precursors, whereby oxygen vacancies in the precursors induce controlled moderate Li/Ni mixing, while their enhanced specific-surface-area property enables dense amorphous Li<sub>2</sub>CO<sub>3</sub> encapsulation. The optimal Li/Ni mixing harnesses the Ni pillar effect to stabilize the structure of cathodes upon cycling. Additionally, amorphous Li<sub>2</sub>CO<sub>3</sub> coating serves not only as a thermodynamically stable and air-impermeable protective layer for the cathodes, but as a transformative precursor for an F-rich cathode electrolyte interphase (CEI) which enhances interfacial stability and electrochemical properties. This dual-modulated cathode delivers a high discharge capacity of 215.1 mA h g<sup>−1</sup> at 0.1 C, retains 84.9% capacity after 200 cycles at 1 C in half cells, and achieves 96.0 mA h g<sup>−1</sup> at 8 C in full-cell tests. Furthermore, we unravel the potential mechanism of Ni pillar effect from optimal Li/Ni mixing and track the evolution mechanism of Li<sub>2</sub>CO<sub>3</sub> coating into F-rich CEI.
