At present, in response to the call of green and renewable energy industry, electrical storage systems have been vigorously developed supported. Electrochemical are mostly comprised batteries, which outstanding advantages such as high density conversion efficiency. Among them, secondary batteries like lithium sodium lead-acid received wide attention recent years. Lithium-ion (LIBs) existed for a long time. However, due limited resources worldwide, uneven distribution, worrying safety issues, development LIBs has gradually hindered. Meanwhile, sodium-ion (SIBs), whose working principle is similar that LIBs, emphasized by researchers abundant low cost. Moreover, all-solid-state (ASSBs), higher density, simpler structure, stability safety, also under rapid development. Thus, SIBs ASSBs both expected play important roles applications.

Abstract Sodium‐ion batteries (NIBs) emerge as promising alternatives to lithium‐ion due sodium's abundance, low cost, and sustainability. However, NIBs face challenges such lower energy density, electrode material compatibility, long‐term stability. Anode‐free sodium (AFNBs) address these limitations by eliminating the pretreatment anode, using a current collector for plating stripping, thus increasing density simplifying manufacturing. Several types of AFNBs, including anode‐free Na‐metal, Na‐solid‐state, Na‐air/CO 2 batteries, are under development, each targeting specific electrochemical challenges. Na‐metal offer high but suffer from dendrite formation unstable solid‐electrolyte interphase (SEI). Na‐solid‐state enhance safety issues with interfacial resistance limited ionic conductivity. promise exceptional densities still in early stages, struggle Na lose stability concerns. Interface engineering plays crucial role overcoming challenges, particularly controlling deposition, stabilizing SEI, minimizing side reactions. Research focuses on optimizing interface through surface modifications, electrolyte composition, protective coatings suppress cycling This review highlights latest advancements explores future directions aiming develop high‐energy‐density, durable, safe sodium‐based storage systems.
