Room-temperature sodium−sulfur (RT Na−S) batteries are considered to be a competitive electrochemical energy storage system, due to their advantages in abundant natural reserves, inexpensive materials, and superb theoretical energy density. Nevertheless, RT Na−S batteries suffer from a series of critical challenges, especially on the S cathode side, including the insulating nature of S and its discharge products, volumetric fluctuation of S species during the (de)sodiation process, shuttle effect of soluble sodium polysulfides, and sluggish conversion kinetics. Recent studies have shown that nanostructural designs of S-based materials can greatly contribute to alleviating the aforementioned issues via their unique physicochemical properties and architectural features. In this review, we review frontier advancements in nanostructure engineering strategies of S-based cathode materials for RT Na−S batteries in the past decade. Our emphasis is focused on delicate and highly efficient design strategies of material nanostructures as well as interactions of component−structure−property at a nanosize level. We also present our prospects toward further functional engineering and applications of nanostructured S-based materials in RT Na−S batteries and point out some potential developmental directions.
The accomplishment of high-performance room-temperature sodium-sulfur (RT Na-S) batteries necessitates multifunctional sulfur electrodes via decent materials design strategies, since they are suffering from a series of critical challenges from S...
