However, competition for decomposition between additives and solvents hampers the preferential reduction of additives and diminishes their effectiveness. Herein, we propose an interfacial interaction-driven strategy to selectively regulate the decomposition behavior and maximize the utility of fluoroethylene carbonate (FEC) for constructing a robust NaF-rich SEI for stable sodium-metal batteries (SMBs). An in-situ formed Na<sub>3</sub>Bi alloy on the Na anode surface exhibits stronger adsorption affinity toward FEC compared to carbonate solvents, leading to FEC enrichment within the electric double layer at the anode surface. Benefiting from the enhanced interfacial interaction, the Na<sub>3</sub>Bi alloy facilitates preferential reductive decomposition of FEC and maximizes FEC utilization, resulting in a dense, gradient-structured NaF-rich SEI. Furthermore, the sodiophilic Na<sub>3</sub>Bi alloy effectively homogenizes Na nucleation and enables non-dendritic Na deposition. Importantly, the Na<sub>3</sub>Bi alloy maintains structural and chemical stability during prolonged cycling, ensuring sustained interfacial regulation. As a result, the modified Na anodes deliver excellent cycling stability in Na||Na symmetric cells. Moreover, the Na||Na<sub>3</sub>V<sub>2</sub>(PO<sub>4</sub>)<sub>3</sub> (NVP) cells achieve an ultra-long lifespan exceeding 10,000 cycles at 5 C.

However, its practical application is hindered by limited rate performance, rapid capacity fading and poor all-climate adaptability, which are closely related to electrode kinetics and structural stability. Herein, a synergistic strategy combining charge redistribution with local crystal reconstruction is proposed by the introduction of rare earth (RE) elements, enhancing the charge transport kinetics and structural stability of NFPO, thereby boosting its comprehensive performance and all-climate adaptability. Specifically, by introducing RE that are more prone to losing electrons at the Fe sites, the pinning effect of RE could reconstruct the local structure of TMO<sub>6</sub>, thus enhancing the structural stability of NFPO for high-temperature tolerance.
