Innovative rechargeable batteries that can effectively store renewable energy, such as solar and wind power, urgently need to be developed to reduce greenhouse gas emissions. All-solid-state batteries with inorganic solid electrolytes and electrodes are promising power sources for a wide range of applications because of their safety, long-cycle lives and versatile geometries. Rechargeable sodium batteries are more suitable than lithium-ion batteries, because they use abundant and ubiquitous sodium sources. solid electrolytes are critical for realizing allsolid-state sodium batteries. Here we show that stabilization of a high-temperature phase by crystallization from the glassy state dramatically enhances the na + ion conductivity. An ambient temperature conductivity of over 10 − 4 s cm − 1 was obtained in a glass-ceramic electrolyte, in which a cubic na 3 Ps 4 crystal with superionic conductivity was first realized. All-solid-state sodium batteries, with a powder-compressed na 3 Ps 4 electrolyte, functioned as a rechargeable battery at room temperature.

First principles computational techniques are used to study properties of promising Li ion electrolytes, recently developed at Oak Ridge National Laboratory, based on alloys having the composition Li3 + xAs1 − xGexS4. The crystal structure of pure Li3AsS4 is found to be characterized by the Pmn21 space group. Based on modifications of this structure, reasonable models of the x = 1/4 and x = 1/3 alloys are found to be in good agreement with the experimental X-ray diffraction patterns and to be consistent with the measured trends in Li ion conduction. As a consequence of their Pmn21-based structures, interstitial and interstitialcy mechanisms are found to be important for the Li ion conduction processes in these systems.

Recent realization of high sodium‐ion conductivities (>10−2 S cm−1) in inorganic solid electrolytes (ISEs) at room temperature will certainly trigger a boom in all‐solid‐state sodium batteries (ASS‐SBs). However, their electrochemical stable windows and compatibility to high capacity/voltage electrodes are unsatisfactory. Developing ideal ISEs that deliver high Na+ ion conductivities, good electrochemical/chemical stability, and compatible electrode/ISE interface is key for the success of high‐performance ASS‐SBs. In this review, focus is mainly on the fundamentals and strategies to optimize ASS‐SB performances from the aspects of ISE and interface, and note that interfacial issues are also ISE‐related. The latest progress in ISEs, including fundamentals of the sodium‐ion conduction mechanism, key parameters dominating the Na+ ion conduction in terms of crystal structure, lattice dynamics, point defects, and grain boundaries, and prototyping strategies for cell design, are elaborated from the perspectives of material and defect chemistry. The key challenges and future opportunities are discussed, and rational solutions are provided.
