This paper presents a systematic review of studies in the design of carbon-based host materials for room-temperature sodium-sulfur batteries.Firstly,it described the electrochemical working principle of room temperature sodium-sulfur cells,introduced the key issues facing by room sodium-sulfur cells,and demonstrated some of the common tools recently proposed for the design and improvement of sulfur cathode levels,such as nanostructural constraints,non-metallic heteroatom doping,metallic mono-atom doping,and heterostructures in adsorption-catalysis synergies.These designs addressed the critical issues of polysulfide shuttling effects and slow electrode kinetics of sodium oxidation and sulfur reduction from different perspectives.Finally,certain research perspectives were presented for the practical application needs of the sulfur ortho-grade carbon-based hosts for room-temperature sodium-sulfur batteries.
