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 high-performance sulfur hosts for Li-S batteries. © 2024 Elsevier B.V.

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 :

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 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

Crystalline and amorphous Fe2O3 nanocubes grown on electrospun carbon nanofibers for lithium-ion batteries and lithium-sulfur batteries: A comparative study SCIE

Abstract&Keyword Cite Version(2)

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 :

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

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 :

Inevitable dissolution in aqueous electrolytes, intrinsically low electrical conductivity, and sluggish reaction kinetics have significantly hampered the zinc storage performance of vanadium oxide-based cathode materials. Herein, core-shell N-doped carbon-encapsulated amorphous vanadium oxide arrays, prepared via a one-step nitridation process followed by in situ electrochemical induction, as a highly stable and efficient cathode material for aqueous zinc-ion batteries (AZIBs) are reported. In this design, the amorphous vanadium oxide core provides unobstructed ions diffusion routes and abundant active sites, while the N-doped carbon shell can ensure efficient electron transfer and greatly stabilize the vanadium oxide core. The assembled AZIBs exhibit remarkable discharge capacity (0.92 mAh cm(-2) at 0.5 mA cm(-2)), superior rate capability (0.51 mAh cm(-2) at 20 mA cm(-2)), and ultra-long cycling stability (approximate to 100% capacity retention after 500 cycles at 0.5 mA cm(-2) and 97% capacity retention after 10 000 cycles at 20 mA cm(-2)). The working mechanism is further validated by in situ X-ray diffraction combined with ex situ tests. Moreover, the fabricated cathode is highly flexible, and the assembled quasi-solid-state AZIBs present stable electrochemical performance under large deformations. This work offers insights into the development of high-performance amorphous vanadium oxide-based cathodes for AZIBs.
