All‐solid‐state sodium ion batteries (ASSIBs) have attracted great attention due to ever‐increasing safety concern about current lithium ion batteries and the limited natural reserves of lithium. A major materials basis to enable high‐performance ASSIBs lies in delivering ultra‐fast Na + conductors, which is yet even more challenging than developing solid electrolytes for the lithium‐ion batteries. This is largely attributed to limited fundamental understanding of the transportation characteristics of sodium ions, which is rather different from the smaller alkali lithium ions. Here, we have carried out a perspective review of recent advances in theoretical formulation of novel solid electrolytes, focusing on methods, achievements, and the potential and shortcomings of identified materials systems. Efforts are made in offering a dependable framework to formulate fundamentally competitive materials to support developing “better” solid sodium‐ion batteries.
