“…What's more, the simple and low‐cost preparation process compared with nitrides, borides and carbides endows the phosphides with great potential as the electrocatalytic material applied in LSBs. [ 35,110 ] The recent explorations have clarified the underlying mechanisms of metal phosphides from molecular level in the aspect of regulating LiPS evolution. Up to now, varieties of metal phosphides such as MoP, CoP, FeP, Ni 2 P, and Co–Fe–P have aroused considerable interests and investigations in the field of Li–S system.…”

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.

“…3D-rGO with host Li 2 S 6 catholyte has been also used with discharge capacity 1607 mAh g −1 at 0.1 C and efficiency of over 200 cycles with sulfur loading 6.6 mg cm −2 [94]. Designed sulfur cathodes using Gp with the effect of particle sizes of 13 µm and 500-1000 nm [95], Gp embedded WS 2 nanoclusters (degradation 0.067% per cycle at 1 C during 250 cycles) with sulfur loading (10.83 mg cm −2 ) [96], and Gp sheets grafted with Ni 12 P 5 nanoparticles (degradation 0.074%/cycle at 1 C during 500 cycles) with sulfur loading (3.5 mg cm −2 ) [97], have also been reported.…”

Graphene, a 2D carbon structure, due to its unique materials characteristics for energy storage applications has grasped the considerable attention of scientists. The highlighted properties of this material with a mechanically robust and highly conductive nature have opened new opportunities for different energy storage systems such as Li-S (lithium-sulfur), Li-ion batteries, and metal-air batteries. It is necessary to understand the intrinsic properties of graphene materials to widen its large-scale applications in energy storage systems. In this review, different routes of graphene synthesis were investigated using chemical, thermal, plasma, and other methods along with their advantages and disadvantages. Apart from this, the applications of N-doped graphene in energy storage devices were discussed.

“…Recently, varieties of catalytic materials based on metal nanoparticles (Pt, Co) and transition‐metal oxides, sulfides, nitrides, and phosphides et al. have been proposed to lower the Li 2 S nucleation/decomposition energy barrier and therefore enhance the reaction kinetics of LSBs [13–18] . Nevertheless, considering the zero‐capacity contribution of catalytic materials in the Li‐S battery system, the maximum utilization of catalytic materials is expected to achieve by fully exposing the catalytic active sites.…”

Use of catalytic materials is regarded as the most desirable strategy to cope with sluggish kinetics of lithium polysulfides (LiPSs) transformation and severe shuttle effect in lithium-sulfur batteries (LSBs). Single-atom catalysts (SACs) with 100 %a tom-utilization are advantagous in serving as anchoring and electrocatalytic centers for LiPSs.H erein, an ovel kind of tungsten (W) SACi mmobilized on nitrogendoped graphene (W/NG) with au nique W-O 2 N 2 -C coordination configuration and ah igh Wl oading of 8.6 wt %i s proposed by as elf-template and self-reduction strategy.T he local coordination environment of Watom endows the W/NG with elevated LiPSs adsorption ability and catalytic activity. LSBs equipped with W/NG modified separator manifest greatly improved electrochemical performances with high cycling stability over 1000 cycles and ultrahigh rate capability. It indicates high areal capacity of 6.24 mAh cm À2 with robust cycling life at ahigh sulfur mass loading of 8.3 mg cm À2 .
