“…The interfaces between the cathodes, anodes and the electrolyte are also one of the factors that affect the electrochemical performance of ASSBs. How to achieve both high ionic conductivity and a stable interface is an urgent research topic that needs to be addressed; 133 In addition, the sodium insertion process can easily induce nonconservative changes or even irreversible structural failures in electrode materials, which are likely to greatly reduce the cycle stability of the battery. 134 Therefore, the development of suitable electrolyte materials that can adapt to the rapid and stable insertion/ extraction of Na + has become a key focus in the industrial development of ASSBs, and it is also the primary focus of this Review.…”

At present, in response to the call of the green and renewable energy industry, electrical energy storage systems have been vigorously developed and supported. Electrochemical energy storage systems are mostly comprised of energy storage batteries, which have outstanding advantages such as high energy density and high energy conversion efficiency. Among them, secondary batteries like lithium batteries, sodium batteries, and lead-acid batteries have received wide attention in recent years. Lithium-ion batteries (LIBs) have existed for a long time. However, due to limited lithium resources worldwide, uneven distribution, and worrying safety issues, the development of LIBs has been gradually hindered. Meanwhile, sodium-ion batteries (SIBs), whose working principle is similar to that of LIBs, have been gradually emphasized by researchers due to the advantages of abundant resources and low cost. Moreover, all-solid-state sodium batteries (ASSBs), which have higher energy density, simpler structure, and higher stability and safety, are also under rapid development. Thus, SIBs and ASSBs are both expected to play important roles in green and renewable energy storage applications. This Review focuses mainly on the detailed introduction of the constituent materials of SIBs and ASSBs, analyzing the development of cathode and anode materials and the solid-state electrolytes (SSEs) in the past five years. The advantages and development direction of each SSE suitable for ASSBs are listed and remarked, and the nonactive materials such as separators and collectors are briefly mentioned. Finally, a reasonable assessment and prospects of the different materials and preparation methods are put forward.

Developing argyrodite-type, chlorine-rich, sodium-ion, solid-state electrolytes with high conductivity is a long-term challenge that is crucial for the advancement of all-solid-state batteries (ASSBs). In this study, chlorine-rich, argyrodite-type Na6−xPS5−xCl1+x solid solutions were successfully developed with a solid solution formation range of 0 ≤ x ≤ 0.5. Na5.5PS4.5Cl1.5 (x = 0.5), displaying a highest ionic conductivity of 1.2 × 10–3 S/cm at 25 °C, which is more than a hundred times higher than that of Na6PS5Cl. Cyclic voltammetry and electrochemical impedance spectroscopy results demonstrated that the rich chlorine significantly enhanced the ionic conductivity and electrochemical stability, in addition to causing a reduction in activation energy. The Na5.5PS4.5Cl1.5 composite also showed the characteristics of a pure ionic conductor without electronic conductivity. Finally, the viability of Na5.5PS4.5Cl1.5 as a sodium electrolyte for all-solid-state sodium batteries was checked in a lab-scale ASSB, showing stable battery performance. This study not only demonstrates new composites of sodium-ionic, solid-state electrolytes with relatively high conductivity but also provides an anion-modulation strategy to enhance the ionic conductivity of argyrodite-type sodium solid-state ionic conductors.
