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.
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.
Among the sodium-ion (Na +) conducting solid electrolytes, Na-β″-alumina (BASE) is highly regarded for its employment in solid-state battery applications due to its high ionic conductivity and electrochemical stability. BASE has long been employed in commercial Na–NiCl 2 and Na–S batteries.
In most cases the electrolyte is a dense solid β″-Al 2 O 3 sodium ion-conducting membrane. The issues prohibiting widespread commercialization of sodium-beta alumina technology are related to the materials and methods of manufacturing that impact cost, safety, and performance characteristics.
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).
In a three-electrode study, the processes of plating and stripping were separated in a Na/BASE/Na cell at room temperature, which undoubtedly deepens the understanding of the interface processes between a sodium metal electrode and sodium-beta alumina electrolyte. Na worked both as counter, reference, and the working electrode.
