Recent progress of ceramic electrolytes for post Li and Na batteries

Recently, post Li batteries have been intensively researched due to high cost and localization of Li sources, especially for large-scale applications. Concurrently, ceramic electrolytes for post Li batteries also gain much attention to develop all-solid-state post Li batteries. The most intensively researched post Li battery is Na battery because of chemical and electrochemical similarities between Li and Na elements. Many good review papers about Na battery have been published including Na-ion conductive ceramic electrolytes. Contrary, ceramic electrolytes for other post Li batteries like K, Mg, Ca, Zn and Al batteries are hardly summarized. In this review, research on ceramic electrolytes for K, Mg, Ca, Zn and Al batteries is analyzed based on latest papers published since 2019 and suggested future research direction of ceramic electrolytes for post-Li batteries.
