All-solid-state sodium (Na)-metal batteries (ASSSMBs) are considered promising candidates for large-scale energy storage systems due to their abundant resources, unparalleled safety performance, and impressive density. Na superionic conductors (NASICONs) among the best enablers of ASSSMBs in view high ionic conductivity, ease synthesis, excellent thermal stability good electrochemical/chemical compatibility with common electrodes. However, challenges surrounding NASICON/electrode interface, such as interfacial resistance dendrite formation, have hindered development practical based on NASICONs. This review starts an explicit summary interface problems between metallic anode NASICON arising from mechanical, chemical, electrochemical aspects (i.e., poor contact, insulating side-reaction products, irregular growth). Subsequently, we systematically analyze logically categorize modification strategies addressing provide a comprehensive discussion underlying enhancement mechanisms. As such, identify universal mechanisms by comparatively studying various strategies. Furthermore, briefly summarize cathode/electrolyte early-stage research efforts constructing stable fabricating high-performance composite cathodes. Finally, key suggestions future prospectives advancement NASICON-based outlined.

Abstract Sodium metal is regarded as an optimal anode material for high‐energy‐density sodium‐ion batteries (SIBs). However, during the processes of sodium deposition and stripping, failure solid electrolyte interphase (SEI) film leads to continuous accumulation inactive sodium, thereby compromising cycling reversibility battery. Here, a novel fluoride heterointerface layer generated constructed through in situ manipulation reaction between TiF 4 Na. The reconstructed NaF/TiF 3 interface layer, which tightly anchors metal, effectively suppresses formation dendrites charge‐discharge process. highly sodium‐philic component exhibits strong binding with Na ions, while NaF reduces + diffusion energy barrier, significantly enhancing kinetics. Due successful artificial construction this Na/TiF composite electrode demonstrates exceptional ultra‐long stability 2370 h symmetric cells (0.5 mAh cm −2 ). Density functional theory (DFT) calculations further validate functionality each protective layer. When paired NaNi 1/3 Fe Mn O 2 cathode pouch cell, it up 2000 cycles at current densities C C, maximum density output 483.1 Wh kg −1 (power density: 320.8 W
