“…Furthermore, the grain size remains constant after conversion [28] . Vapor phase synthesis was chosen from different groups for the fabrication of sodium‐beta alumina [88–91] . Nano‐η‐alumina can be used to synthesize β′′‐alumina by a vapor phase process [91] and γ‐Al 2 O 3 instead of α‐Al 2 O 3 can be used for synthesis to overcome a large amount of β′′‐alumina powder since γ‐Al 2 O 3 and sodium‐β′′‐alumina exhibit similar structures.…”

Sodium‐based batteries are promising post lithium‐ion technologies because sodium offers a specific capacity of 1166 mAh g−1 and a potential of −2.71 V vs. the standard hydrogen electrode. The solid electrolyte sodium‐beta alumina shows a unique combination of properties because it exhibits high ionic conductivity, as well as mechanical stability and chemical stability against sodium. Pairing a sodium negative electrode and sodium‐beta alumina with Na‐ion type positive electrodes, therefore, results in a promising solid‐state cell concept. This review highlights the opportunities and challenges of using sodium‐beta alumina in batteries operating from medium‐ to low‐temperatures (200 °C–20 °C). Firstly, the recent progress in sodium‐beta alumina fabrication and doping methods are summarized. We discuss strategies for modifying the interfaces between sodium‐beta alumina and both the positive and negative electrodes. Secondly, recent achievements in designing full cells with sodium‐beta alumina are summarized and compared. The review concludes with an outlook on future research directions. Overall, this review shows the promising prospects of using sodium‐beta alumina for the development of solid‐state batteries.

Solid‐state sodium batteries (SSSBs) are poised to replace lithium‐ion batteries as viable alternatives for energy storage systems owing to their high safety and reliability, abundance of raw material, and low costs. However, as the core constituent of SSSBs, solid‐state electrolytes (SSEs) with low ionic conductivities at room temperature (RT) and unstable interfaces with electrodes hinder the development of SSSBs. Recently, composite SSEs (CSSEs), which inherit the desirable properties of two phases, high RT ionic conductivity, and high interfacial stability, have emerged as viable alternatives; however, their governing mechanism remains unclear. In this review, we summarize the recent research progress of CSSEs, classified into inorganic–inorganic, polymer–polymer, and inorganic–polymer types, and discuss their structure–property relationship in detail. Moreover, the CSSE–electrode interface issues and effective strategies to promote intimate and stable interfaces are summarized. Finally, the trends in the design of CSSEs and CSSE–electrode interfaces are presented, along with the future development prospects of high‐performance SSSBs.

All-solid-state sodium batteries (AS 3 B) emerged as a strong contender in the global electrochemical energy storage market as a replacement for current lithium-ion batteries (LIB) owing to their high abundance, low cost, high safety, high energy density, and long calendar life. Inorganic electrolytes (IEs) are highly preferred over the conventional liquid and solid polymer electrolytes for sodium-ion batteries (SIBs) due to their high ionic conductivity (∼10 −2 −10 −4 S cm −1 ), wide potential window (∼5 V), and overall better battery performances. This review discusses the bird's eye view of the recent progress in inorganic electrolytes such as Na-β"alumina, NASICON, sulfides, antipervoskites, borohydride-type electrolytes, etc. for AS 3 Bs. Current state-of-the-art inorganic electrolytes in correlation with their ionic conduction mechanism present challenges and interfacial characteristics that have been critically reviewed in this review. The current challenges associated with the present battery configuration are overlooked, and also the chemical and electrochemical stabilities are emphasized. The substantial solution based on ongoing electrolyte development and promising modification strategies are also suggested.
