“…One cathode alternative with the best prospects, layered transition metal oxides (LTMOs), has attracted intense research interest, not just because of their non-toxic nature, high theoretical capacity, easy processability, mature manufacturability, suitable voltage, and abundant resources but also because of their potentially low cost. 11–25 LTMOs have P2, P3, O2, and O3 phase and tunnel structures, all of which have advantages and disadvantages. Single-phase materials have been studied a lot, yet the commercial implementation of LTMOs is still limited by their insufficient rate capability, low energy density, insufficient cycling stability, and air instability.…”

All‐solid‐state batteries have drawn a lot of concern owing to their distinct advantages in energy density and safety. However, the interfacial issues between the solid electrolyte and electrodes are still roadblocks to large scale application of rechargeable solid‐state batteries. In this work, it reveals that promoting the Na‐O affinity in Na3Zr2Si2PO12 electrolyte can effectively boost its air stability. Specifically, a two‐step sintering approach is employed to actively regulate the microstructure evolution of Na3Zr2Si2PO12 electrolyte. Apart from the enhanced strength of the Na‐O bond, the mechanical performance and ionic conductivity are also apparently improved in comparison with the traditional one‐step sintering. Moreover, a low resistance of 68 Ω cm2 is achieved with the Na/Na3Zr2Si2PO12 interface, demonstrating long cycling stability of 1000 cycles at 0.1 mA cm−2. The designed Na3Zr2Si2PO12 ceramic electrolyte paired with Na3.5V0.5Mn0.5Fe0.5Ti0.5(PO4)3 cathode and metallic Na anode manifests outstanding cycling stability with a high reversible discharge capacity of 136 mAh g−1 after nearly 400 cycles at 1 C, and 25 °C. Therefore, it is believed that the delicate modulation of solid electrolyte microstructure is of great importance for accelerating the application of solid‐state batteries.

All‐solid‐state sodium batteries are particularly attractive for large‐scale energy storage and electric vehicles due to their exceptional safety, abundant resource availability, and cost‐effectiveness. The growing demand for all‐solid‐state sodium batteries underscores the significance of sodium solid electrolytes. However, the existed challenges of sodium solid electrolytes hinder their practical application despite continuous research efforts. Herein, we review recent advancements and the challenges for sodium solid electrolytes from material to battery level. The in‐depth understanding of their fundamental properties, synthesis techniques, crystal structures and recent breakthroughs are presented. Moreover, critical challenges on inorganic sodium solid electrolytes are emphasized, including the imperative need to enhance ionic conductivity, fortifying interfacial compatibility with anode/cathode materials, and addressing dendrite formation issues. Finally, potential applications of these inorganic sodium solid electrolytes are explored in all‐solid‐state sodium batteries and emerging battery systems, offering insights into future research directions.This article is protected by copyright.
