“…Porous carbon materials, including porous nanofibers, microporous carbons, and carbon nanotubes, have been used to confine elemental sulfur, aiming to solve the aforementioned issues in Na–S batteries. In particular, hollow carbon spheres (HCSs) with a huge void space and porous shell are expected to immobilize a high amount of active sulfur and suppress polysulfide dissolution into the liquid electrolyte. − However, there are still many inherent disadvantages when using HCSs as the sulfur hosts, such as the uneven distribution of sulfur inside the cavity and the lack of conductivity for the internal sulfur, which result in instability of materials and low sulfur activity . Meanwhile, the structural stability of hollow carbon needs to be further strengthened to accommodate the stress change during the repeated uptake/release of sodium ions .…”

Intricate hollow carbon structures possess vital function for anchoring polysulfides and enhancing the utilization of sulfur in room-temperature sodium–sulfur batteries. However, their synthesis is extremely challenging due to the complex structure. Here, a facile and efficient strategy is developed for the controllable synthesis of N/O-doped multichambered carbon nanoboxes (MCCBs) by selective etching and stepwise carbonization of ZIF-8 nanocubes. The MCCBs consist of porous carbon shells on the outside and connected carbon grids with a hollow structure on the inside, bringing about a MCCBs structure. As a sulfur host, the multichambered structure has better spatial encapsulation and integrated conductivity via the inner interconnected carbon grids, which combines the characteristics of short charge transfer path and superb physicochemical adsorption along with mechanical strength. As expected, the S@MCCBs cathode realizes decent cycle stability (0.045% capacity decay per cycle over 800 cycles at 5 A g–1) and enhanced rate performance (328 mA h g–1 at 10 A g–1). Furthermore, in situ transmission electron microscopy (TEM) observation confirms the good structural stability of the S@MCCBs during the (de)sodiation process. Our work demonstrates an effective strategy for the rational design and accurate construction of intricate hollow materials for high-performance energy storage systems.

“…The polar nanoparticles uniformly dispersed on the surface of carbon materials only provide limited active sites, which are sufficient to adsorb and catalyze a small amount of NaPSs. [ 85 ] A lot of NaPSs still dissolve in the electrolyte and thereby cannot undergo reversible conversion, especially at high sulfur loading. Herein, the constructed hollow polar structure is ideal host material.…”

Room temperature sodium–sulfur (RT Na‐S) battery with high theoretical energy density and low cost has spurred tremendous interest, which is recognized as an ideal candidate for large‐scale energy storage applications. However, serious sodium polysulfide shutting and sluggish reaction kinetics lead to rapid capacity decay and poor Coulombic efficiency. Recently, catalytic materials capable of adsorbing and catalyzing the conversion of polysulfides are profiled as a promising method to improve electrochemical performance. In this review, the research progress is summarized that the application of catalytic materials in RT Na‐S battery. For the role of catalyst on the conversion of sulfur species, specific attention is focused on the influence factors of reaction rate during different redox processes. Various catalytic materials based on lightweight and high conductive carbon materials, including heteroatom‐doped carbon, metals and metal compounds, single‐atom and heterostructure, promote the reaction kinetic via lowered energy barrier and accelerated charge transfer. Additionally, the adsorption capacity of the catalytic materials is the key to the catalytic effect. Particular attention to the interaction between polysulfides and sulfur host materials is necessary for the exploration of catalytic mechanism. Lastly, the challenges and outlooks toward the desired design of efficient catalytic materials for RT Na‐S battery are discussed.
