“…In order to pursue higher sulfur conversion rate and efficiency, Li and co‐workers successfully realized the phase transformation from MoP to Mo 4 P 3 with higher intrinsic catalytic performance toward LiPSs through the introduction of Ruthenium (Ru). [ 113 ] The author reasoned that more exposed Mo sites in Mo 4 P 3 with a higher metal/P ratio than MoP favorably provided rapid ion diffusion and charge transfer dynamics. The hollow carbon spheres decorated with Mo 4 P 3 nanoparticles used as an effective sulfur loading material to exhibit a fantastic rate capability of 660 mAh g −1 at 4 C, which outperformed other transition metal phosphides for LSBs ever reported.…”

Lithium–sulfur batteries (LSBs) with a high theoretical capacity of 1675 mAh g−1 hold promise in the realm of high‐energy‐density Li–metal batteries. To cope with the shuttle effect and sluggish transformation of soluble lithium polysulfides (LiPSs), varieties of traditional metal‐based materials (such as metal, metal oxides, metal sulfides, metal nitrides, and metal carbides) with unique catalytic activity for accelerating LiPSs redox have been exploited to fundamentally inhibit the shuttle effect and improve the performance of LSBs. Concurrently, some budding catalytic materials also possess enormous potential for facilitating LiPSs redox reaction in LSBs, including metal borides, metal phosphides, metal selenides, single atoms, and defect‐engineered materials. Here, recent advances in these emerging catalytic candidates as well as the evaluation methods and parameters for catalytic materials are comprehensively summarized for the first time. New insights are also given to aid in the design of high‐performance LSBs and satisfy the high expectation in the future, including the exposure of the active sites and adsorption‐catalysis synergy strategies. Finally, the current challenges and prospects for designing highly efficient catalytic materials are highlighted, aiming at providing guidance for configuring catalytic materials to make sure high‐energy and long‐life LSBs.

Metal‐sulfur batteries (MSBs) are considered up‐and‐coming future‐generation energy storage systems because of their prominent theoretical energy density. However, the practical applications of MSBs are still hampered by several critical challenges, i.e., the shuttle effects, sluggish redox kinetics, and low conductivity of sulfur species. Recently, benefiting from the high surface area, regulated networks, molecular/atomic‐level reactive sites, the metal‐organic frameworks (MOFs)‐derived nanostructures have emerged as efficient and durable multifaceted electrodes in MSBs. Herein, a timely review is presented on recent advancements in designing MOF‐derived electrodes, including fabricating strategies, composition management, topography control, and electrochemical performance assessment. Particularly, the inherent charge transfer, intrinsic polysulfide immobilization, and catalytic conversion on designing and engineering of MOF nanostructures for efficient MSBs are systematically discussed. In the end, the essence of how MOFs’ nanostructures influence their electrochemical properties in MSBs and conclude the future tendencies regarding the construction of MOF‐derived electrodes in MSBs is exposed. It is believed that this progress review will provide significant experimental/theoretical guidance in designing and understanding the MOF‐derived nanostructures as multifaceted electrodes, thus offering promising orientations for the future development of fast‐kinetic and robust MSBs in broad energy fields.

“…Phase engineering and heteroatom doping are considered two effective strategies to adjust the properties of the catalyst [ 128 , 129 ]. Following this idea, Ma et al transformed MoP to Mo 4 P 3 via Ru doping (Ru-Mo 4 P 3 ) and demonstrated that Ru-Mo 4 P 3 can effectively facilitate the electrocatalytic conversion of LiPSs (Figures 17(c) – 17(f) ) [ 127 ]. The separation between the cathodic and anodic peaks was ~0.18 V for the devices composed of HCS-Ru-Mo 4 P 3 , suggesting an accelerated LiPS conversion.…”

Lithium-sulfur (Li-S) batteries as power supply systems possessing a theoretical energy density of as high as 2600 Wh kg−1 are considered promising alternatives toward the currently used lithium-ion batteries (LIBs). However, the insulation characteristic and huge volume change of sulfur, the generation of dissolvable lithium polysulfides (LiPSs) during charge/discharge, and the uncontrollable dendrite formation of Li metal anodes render Li-S batteries serious cycling issues with rapid capacity decay. To address these challenges, extensive efforts are devoted to designing cathode/anode hosts and/or modifying separators by incorporating functional materials with the features of improved conductivity, lithiophilic, physical/chemical capture ability toward LiPSs, and/or efficient catalytic conversion of LiPSs. Among all candidates, molybdenum-based (Mo-based) materials are highly preferred for their tunable crystal structure, adjustable composition, variable valence of Mo centers, and strong interactions with soluble LiPSs. Herein, the latest advances in design and application of Mo-based materials for Li-S batteries are comprehensively reviewed, covering molybdenum oxides, molybdenum dichalcogenides, molybdenum nitrides, molybdenum carbides, molybdenum phosphides, and molybdenum metal. In the end, the existing challenges in this research field are elaborately discussed.
