Abstract ：
Delicate design high-efficiency sulfur electrocatalysts is crucial for suppressing the shuttle effect of soluble lithium polysulfides (LiPSs) and improving the electrochemical performance in lithium-sulfur (Li-S) electrochemistry. Herein, a self-supported hierarchical NiCo2Se4@Ni0.85Se/MoSe2 electrocatalyst with abundant heterointerfaces and anion vacancies that directly grows on carbon cloth is elaborately designed to accelerate the sulfur redox reaction kinetics effectively. Noteworthy, the abundant heterointerfaces coupling with anion vacancies greatly facilitate the electron transfer, strengthen the chemical adsorption, provide sufficient active sites, and enhance the catalytic activity. Additionally, the hierarchical hollow arrayed architecture can guide the Li2S deposition, relieve the volume expansion, and maintain the structural stability. Consequently, the Li-S batteries with CC@NiCo2Se4@Ni0.85Se/MoSe2 exhibit exceptional electrochemical performance and high sulfur utilization even under high sulfur loading. More importantly, the pouch cells are fabricated to demonstrate the potential for practical applications. Furthermore, the integration of experimental and computational studies confirms that the Ni0.85Se/MoSe2 heterostructure possesses stronger chemical adsorption and reduced energy barrier for LiPSs conversion than MoSe2. Interestingly, it is also discovered that the incorporation of Ni0.85Se promotes the in situ lithium ions intercalation in MoSe2, which is conductive to further performance enhancement. This study provides new inspiration for the hierarchical engineering of electrocatalysts toward high-performance Li-S batteries. © 2025 Wiley-VCH GmbH.

Abstract ：
The sluggish reaction kinetics and formidable shuttle effect of soluble lithium polysulfides (LiPSs) are thorny problems for the future industrialization of lithium-sulfur (Li-S) batteries. Therefore, exploring efficient electrocatalysts to capture LiPSs and accelerate their conversion is highly desirable yet tremendously challenging. Herein, a high-efficiency Bi/Bi2O3/VMoN@rGO electrocatalyst with multifunctional active sites and multilevel heterointerfaces is elaborately designed for Li-S batteries. Noteworthy, the multilevel heterointerfaces can greatly modulate the electron distribution, facilitate the charge transfer, optimize the chemical absorption, and enhance the intrinsic activity, while rGO contributes to high electrical conductivity, sufficient active sites, and robust structural stability. Thanks to the synergy of different components, Li-S batteries employing the Bi/Bi2O3/VMoN@rGO functional separators exhibit impressive electrochemical performance and high sulfur utilization even under high sulfur loading. More importantly, it is discovered that Bi and Bi2O3 experience an electrochemical phase evolution to generate Bi2S3 with amorphous and crystalline phases, thereby bringing in unexpected performance enhancement. Furthermore, experimental results and theoretical calculations authenticate that a reduced Li2S decomposition energy barrier is achieved after the in situ electrochemical reconstruction. This work not only provides new mechanistic insights into developing high-efficiency sulfur electrocatalysts but also sheds light on regulating the catalytic activity via self-reconstruction.

Abstract ：
Lithium-sulfur (Li-S) batteries are considered as one of the most promising energy storage systems. However, the poor electrical conductivity of sulfur and Li2S, sluggish sulfur redox kinetics, shuttle effect of soluble lithium polysulfides (LiPSs), and dendrites growth on Li anode severely preclude their practical applications. Herein, a heterostructured Ni3Se4/FeSe2 tandem electrocatalyst directly grown on the electrospun carbon nanofibers (denoted as CNF@Ni3Se4/FeSe2) is demonstrated to efficiently capture soluble LiPSs and catalyzing their consecutive conversion. The designed CNF@Ni3Se4/FeSe2 interlayer possesses various advantages including high electrical conductivity, abundant catalytic active sites, strong chemisorption capability, and superior catalytic activities. Furthermore, theoretical calculations not only confirm that the formation of Ni3Se4/FeSe2 heterostructure is beneficial for fast charge transfer and enhanced LiPSs adsorption capability, but also reveal the FeSe2 and Ni3Se4 are conductive to consecutively catalyze the reduction of long-chain and short-chain polysulfide intermediates, respectively. Consequently, Li-S batteries assembled with the CNF@Ni3Se4/FeSe2 interlayers deliver remarkable electrochemical performance including high reversible discharge capacity (1412.1 mAh g- 1 at 0.1 C), excellent rate performance (588.0 mAh g- 1 at 5 C) and good long-term cycling stability (capacity fading of 0.058 % per cycle at 2 C after 1000 cycles). More encouragingly, a high initial discharge capacity of 1039.3 mAh g-1 can be obtained even under a high sulfur loading of 4.5 mg cm- 2, indicating the great potential and application prospects. This study provides valuable guidelines for developing advanced tandem catalytic systems in Li-S electrochemistry.

Abstract ：
Amorphous transition metal oxides have recently received particular research interests in electrochemical energy storage. However, there is still a lack of direct comparisons between amorphous materials and their crystalline counterparts. Here, we demonstrate the rational synthesis of crystalline and amorphous Fe2O3 nanocubes uniformly grown on carbon nanofibers (denoted as CNFs@C-Fe2O3 and CNFs@A-Fe2O3, respectively) for lithiumion batteries (LIBs) and lithium-sulfur batteries (LSBs). In such a structure, the Fe2O3 nanocubes possess strong interfacial bonding with CNFs, which can ensure rapid electron transportation. Besides, these Fe2O3 nanocubes are highly porous, which can effectively alleviate the volume change, enlarge the surface area, increase active sites and facilitate ion diffusion. When employed as freestanding anode for LIBs, the CNFs@C-Fe2O3 electrode delivers much improved lithium ion storage performance compared to that of CNFs@A-Fe2O3. When evaluated as interlayers for LSBs, instead, the batteries with CNFs@A-Fe2O3 exhibit better rate performance cycling stability than that of with CNFs@C-Fe2O3. Moreover, theoretical calculations elucidate the amorphous Fe2O3 has stronger adsorption ability toward the soluble lithium polysulfides. This work would provide new insights into the reasonably development of crystalline and amorphous transition metal oxides toward electrochemical energy storage.

Abstract ：
Catalytic conversion of polysulfides has been regarded as an effective strategy to suppress the shuttle effect in lithium-sulfur (Li-S) batteries by accelerating the conversion of lithium polysulfides (LiPSs). However, the rational design of high-performance sulfur electrocatalysts still remains a big challenge. In this work, we develop a facile approach to synthesize a grain-boundary-rich cobalt selenide hollow multi-shelled structure (denoted as GB-CoSe HoMS) to serve as a high-efficiency electrocatalyst for Li-S batteries. Such a unique structural design could physically inhibit the diffusion of polysulfide intermediates and effectively accommodate the large volume expansion. Besides, the GB-CoSe HoMS possesses strong chemical adsorption towards LiPSs and superior catalytic activity to accelerate the conversion reaction kinetics, thereby suppressing the shuttle effect of LiPSs and enhancing the sulfur utilization. Owing to the multifarious advantages, the assembled Li-S batteries with GB-CoSe HoMS modified polypropylene separators display a high initial discharge capacity of 1393.3 mA h g-1 at 0.1C, superior rate performance (660.9 mA h g-1 at 3C), and good long-term cycle stability with a low capacity decay rate of 0.046% per cycle after 1000 cycles at 1C. More significantly, even with a high sulfur loading of 5.5 mg cm-2 and lean electrolyte (E/S approximate to 8.0 mu L mg-1), the battery still harvests a high discharge capacity of 977.8 mA h g-1 after 40 cycles at 0.2C, suggesting its great potential for practical applications. The present work demonstrates the importance of engineering the morphology and grain boundary in developing high-performance electrocatalysts for Li-S batteries. A unique grain-boundary-rich cobalt selenide hollow multi-shelled structure (GB-CoSe HoMS) has been rationally designed and synthesized as a high-efficiency electrocatalyst to adsorb and convert the polysulfides for lithium-sulfur batteries.

Abstract ：
The practical applications of lithium-sulfur (Li-S) batteries are severely impeded by the shuttle effect of soluble lithium polysulfides (LiPSs), sluggish redox reaction kinetics, and insulating nature of sulfur and its discharge products (Li2S2/Li2S). Developing sulfur electrocatalysts with high electrocatalytic activity to accelerate the redox kinetics and polysulfide trapping is critical for Li-S batteries but remains a grand challenge. In this contribution, we demonstrate the delicate design and synthesis of oxygen-incorporated heterophase cobalt vanadium selenide nanoplates with dense crystalline/amorphous interfacial sites (denoted as DC/A O-CoVSe NPs) as high-efficiency sulfur electrocatalysts for Li-S batteries. Such DC/A O-CoVSe NPs possess high electronic conductivity and electrocatalytic activity. Besides, the abundant exposed crystalline/amorphous interfacial sites serve as efficient adsorption-catalytic centers to accelerate the conversion kinetics and alleviate the shuttle effect. Moreover, incorporation of oxygen further increases their affinity to LiPSs because of the introduction of more Li-O interactions. Benefiting from the multifarious advantages, Li-S batteries with DC/A O-CoVSe NP modified separators exhibit high discharge capacity (1400.1 mA h g-1 at 0.1C), excellent rate capability (683.8 mA h g-1 at 5C), and good long-term durability (672.4 mA h g-1 at 1C after 500 cycles with a low decay rate of 0.066% per cycle). Even at a high sulfur loading of 5.6 mg cm-2, the battery still delivers a decent reversible capacity of 658.8 mA h g-1 at 0.2C after 100 cycles, indicating its great potential for practical applications. This work could provide a rational viewpoint for developing high-efficiency sulfur electrocatalysts towards future advanced Li-S energy storage systems. Oxygen-incorporated heterophase cobalt vanadium selenide nanoplates with dense crystalline/amorphous interfacial sites (DC/A O-CoVSe NPs) are developed as high-efficiency sulfur electrocatalysts for lithium-sulfur batteries.

Abstract ：
Lithium-sulfur (Li-S) batteries are promising candidates for next-generation electrochemical energy storage systems by virtue of the high energy density, low-cost, and ecofriendliness. Unfortunately, the sluggish sulfur conversion kinetics, notorious shuttle effect of lithium polysulfides (LiPSs) and severe volumetric variation during the lithiation/delithiation process result in insufficient sulfur utilization and fast capacity degradation. Herein, tungsten-doped vanadium carbide nanosheet arrays strongly coupled with a thin nitrogen-doped carbon layer directly grown on carbon cloth substrate (denoted as CC/W-VC@NC) have been conceptually designed as an advanced sulfur host to resolve the aforementioned problems. Specifically, the binder-free CC/W-VC@NC sulfur host not only strongly interacts with LiPSs, but also presents superior electrocatalytic activity for rapid LiPSs conversion. Additionally, the arrayed architecture provides sufficient space for sulfur loading and simultaneously accommodates its volumetric variation. Furthermore, theoretical calculations elucidate that tungsten doping can regulate the electronic structure, improve the electrical conductivity and strengthen the chemisorption toward LiPSs. Attributing to the multifarious advantages, Li-S batteries assembled with CC/W-VC@NC/ S cathode exhibit a high initial discharge capacity of 1305.9 mAh/g at 0.1 C, as well as superior rate capability (709.8 mAh/g at 5 C) and good long-term durability (capacity decay rate of only 0.063 % per cycle over 500 cycles at 1 C). This study presents an effective approach to construct transition metal carbides as highperformance sulfur hosts for Li-S batteries.

Abstract ：
Lithium-sulfur batteries (LSBs) showcase great promise for large-scale energy storage systems, however, their practical commercialization is seriously hindered by the sluggish redox reaction kinetics and detrimental shuttle effect of soluble polysulfides. Herein, small ZnTe1-x nanoparticles with anionic vacancies firmly anchored on 3D ordered macroporous N-doped carbon skeleton (3DOM-ZnTe1-x@NC) are elaborately constructed as a high-efficiency electrocatalyst for LSBs. The ordered macroporous carbon skeleton not only greatly increases the external surface area to expose sufficient active sites but also facilitates the electrolyte penetration. Additionally, the experimental studies combined with theoretical calculations confirm the presence of Te vacancies optimizes the electronic structure to enhance the intrinsic catalytic activity and chemical absorption. Consequently, LSBs assembled with the 3DOM-ZnTe1-x@NC modified separators exhibit high specific discharge capacity, as well as superior rate performance and good long-term cycling stability. Even under a high sulfur loading of 6.5 mg cm-2 and lean electrolyte, an impressive areal capacity of 5.28 mAh cm-2 is achieved at 0.1 C after 100 cycles. More significantly, the 3DOM-ZnTe1-x@NC based pouch cells are also fabricated to demonstrate its potential for practical applications. This work highlights that the rational combination of 3DOM architecture and vacancy engineering is important for designing advanced Li-S electrocatalysts. Small ZnTe1-x nanoparticles with anionic vacancies anchored on 3D ordered macroporous N-doped carbon skeleton (3DOM-ZnTe1-x@NC) are elaborately constructed to address the challenges of lithium-sulfur batteries (LSBs). Benefiting from the multifarious advantages, LSBs employing 3DOM-ZnTe1-x@NC modified separators exhibit excellent electrochemical performance. This work demonstrates the importance of rational combination of 3DOM architecture and vacancy engineering for designing advanced Li-S electrocatalysts. image

Abstract ：
The intrinsically sluggish sulfur reduction reaction kinetics and serious shuttle effect of soluble lithium polysulfides (LiPSs) severely impede the practical commercialization of lithium-sulfur (Li-S) batteries. Herein, self-supported tungsten nitride and carbide heterostructures with vanadium doping that are directly grown on carbon cloth substrate (CC@V-W2N/WC1-x) are creatively designed for Li-S batteries, which can tandemly catalyze the liquid-liquid conversion and liquid-solid conversion of polysulfide intermediate free of any interference from polymer binders and conductive additives. Noteworthy, the rich heterointerfaces and vanadium doping are beneficial for rapid charge transfer, strong chemical adsorption toward LiPSs, massive exposed catalytically active sites, and remarkable catalytic activities. Consequently, Li-S batteries assembled with the CC@V-W2N/WC1-x/S cathodes exhibit high sulfur utilization, superior rate capability, and decent long-term cycling stability. Furthermore, experimental analyses and theoretical calculations jointly substantiate that the V-W2N component is more effective in catalyzing the conversion of long-chain LiPSs, while the V-WC1-x benefits the favorable Li2S deposition kinetics. More importantly, the Li-S pouch cells are also fabricated to demonstrate their feasibility for practical applications. This work not only highlights the significance of tandem catalysis on the consecutive conversion of LiPSs but also provides a feasible avenue for developing highly efficient electrocatalysts toward high-performance Li-S batteries. A self-supported CC@V-W2N/WC1-x sulfur electrocatalyst with rich heterointerfaces and vanadium doping that is directly grown on carbon cloth substrate is creatively constructed for Li-S batteries. Integrated experimental and theoretical results confirm that the CC@V-W2N/WC1-x can tandemly catalyze the complicated sulfur reduction reaction. This work provides new inspiration for the design of tandem electrocatalysts for Li-S battery system. image

Abstract ：
Rechargeable lithium-sulfur (Li-S) batteries have received ever-increasing attention owing to their ultrahigh theoretical energy density, low cost, and environmental friendliness. However, their practical application is critically plagued by the sluggish reaction kinetics, shuttling of soluble polysulfide intermediates, and uncontrollable growth of Li dendrites. Herein, a bimetallic telluride electrocatalyst with dense heterointerfaces and rich defects embedded in hollow carbon polyhedron bunches (N subset of CoTe1-x/ZnTe1-y@NC, abbreviated as NCZTC) is rationally designed to simultaneously address the S cathode and Li anode problems. Both experimental and computational results substitute the integration of dense heterointerfaces and rich defects can synergistically modulate the electronic structure, enhance the electrical conductivity, promote the Li+ transportation, strengthen the polysulfides adsorption and improve the catalytic activity, thereby significantly accelerating the redox conversion kinetics and prevent the dendrite growth. Consequently, Li-S batteries with NCZTC-modified separators demonstrate excellent electrochemical performance including high specific discharge capacity, remarkable rate capability, good long-term cycling stability, and competitive areal capacity even at high sulfur loading and lean electrolyte conditions. This study not only provides valuable guidance for designing efficient sulfur electrocatalysts with transition metal tellurides but also emphasizes the importance of heterostructure design and defect engineering for high-performance Li-S batteries. The high-efficiency N subset of CoTe1-x/ZnTe1-y@NC electrocatalyst is rationally designed for Li-S batteries. Both experimental and theoretical results substantiate that the integration of dense heterointerfaces and rich defects (Te vacancy-induced N-doping) can synergistically accelerate the sulfur conversion and protect the lithium anode from corrosion. This study provides an innovative strategy for constructing high-performance sulfur electrocatalysts with transition metal tellurides. image
