Sodium (Na) metal anodes suffer from dendrite formation and inferior reversibility, mainly induced by the inhomogeneous nucleation/growth and fragile solid electrolyte interphase (SEI), which hinders their commercial application. Optimizing nucleation behavior or SEI features can improve Na deposition/stripping process, as observed in most currently available approaches, but its long-term cyclic stability remains a great challenge because these issues are not fully optimized/solved in an individual method. Herein, a dual-role crown ether additive (CEA) is introduced into electrolytes to circumvent these challenges concurrently. As revealed by experiments and theoretical calculations, CEA possesses a strong affinity with Na and effectively regulates desolvation kinetics, leading to the uniform Na nucleation/growth. On the other hand, the resultant Na/CEA complexes with a strong Lewis acid feature easily attract anions, which enables an anion-abundant solvation sheath, resulting in a NaF-rich SEI. Consequently, Na|Cu cells deliver a high average Coulombic efficiency of 99.95% beyond one year and stable cyclic stability over 3000 h even under a high depth of discharge (75%), surpassing most previous works. Furthermore, this concept is readily extended to zinc metal batteries, verifying that simultaneous nucleation control and interfacial chemistry regulation are promising ways to realize stable metal anodes.
