“…For instance, materials such as graphene [2] , porous carbon materials [3,4] , metal phosphides [5] , metal oxides [6,7] , and metal selenides [8,9] have been demonstrated to suppresses polysul de dissolution and thereby enhance the electrochemical performance of batteries. Among these, porous carbon is extensively employed in electrode and catalytic materials due to its excellent conductivity and costeffectiveness in fabrication.…”

Lithium-sulfur batteries have not been widely commercialized due to issues with poor conductivity of the active material and the shuttle effect, both of which are effectively addressed in this study. The porous carbon CoNi-NC, derived from high-temperature carbonization of the cobalt-nickel metal-organic framework CoNi-ZIF, was utilized as the carbon substrate. It exhibits excellent specific surface area and a well-developed pore structure, thereby optimizing the conductivity and sulfur-loading capacity of the material. The incorporation of polar Bi2S3 effectively adsorbs polysulfides, retards the shuttle effect, and enhances the reaction kinetics of lithium-sulfur batteries. Electrochemical tests revealed that the CoNi-NC@Bi2S3 electrode achieved a specific discharge capacity of 1107 mAh/g at a current density of 0.1 C, demonstrating excellent rate capability. Moreover, the cathode material maintained a specific discharge capacity of 796.5 mAh/g after 200 cycles at 0.2 C, indicating robust cycling stability.

The seemingly advantageous features of carbon‐based materials, such as large pore volume and lightweight structure, could actually lead to low tap density for the sulfur cathode and excessive electrolyte consumption, potentially significantly decreasing the energy density of lithium–sulfur battery. Recently, non‐carbon‐based materials composed of inorganic matter have emerged as promising candidates for creating dense sulfur cathodes and reducing electrolyte intake. Additionally, inorganic matter exhibits strong interactions with lithium polysulfides, which can address the intrinsic problems of the severe shuttling effect and poor reaction kinetics. In this review, we first discuss the relationship between the tap density of the sulfur cathode and the energy density of lithium–sulfur battery. Subsequently, we systematically summarize recent advances in non‐carbon‐based materials as sulfur hosts. Finally, we propose future research directions and perspectives for sulfur host materials to inspire the realization of practical lithium–sulfur battery with high energy density.
