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.

Rechargeable metal–sulfur batteries with low-cost, soil-rich elemental sulfur as the cathode have attracted considerable attention, as they are crucial for working at room temperature due to their high energy density, high output efficiency, and convenient operation. However, the performance is limited by the low utilization of sulfur, severe volume expansion, and shuttle effect of polysulfides. To address these issues, a key strategy is to design carbon materials with excellent conductivity and high specific surface area, preferably with high chemical affinity and high sulfur loading. In this Review, the fundamentals of room-temperature metal–sulfur batteries and the rational design of carbon sulfur carriers are presented, going into the relationship between carbon sulfur hosts and battery performance. Recent developments are highlighted along with potential directions for future research. This comprehensive review aims to provide guidelines for the design of carbonaceous sulfur hosts and promising methods for the development of high-performance room-temperature metal–sulfur battery systems.
