Lithium metal has considerable advantages as an anode for lithium–sulfur batteries (LSBs). However, LSBs are susceptible to the slow oxidation kinetics of intermediate product polysulfides (LIPSs) and tendency lithium anodes form dendrites during charging discharging. Herein, we constructed a porous rod-like skeleton with metal–organic framework (MOF) main template construct LSB cathodes. ZIF-67 was loaded onto MoO3 nanorods vulcanized CoMoS3.13 rod skeleton. Melamine applied auxiliary carbon source generate highly conductive nanotubes, yielding final hierarchical composites CoMoS3.13@NCNTs. The unique layered hollow structure composite CoMoS3.13@NCNTs, which resulted from excellent exchange synergistic effect bimetallic ions, exerts good physical constraints accelerates transfer transformation LIPSs. On basis above advantages, CoMoS3.13@NCNTs showed electrochemical performance when tested cathode material LSBs, possessing initial discharge specific capacity 1372 mAh g–1 at 0.1 C maintaining low decay rate 0.039% after 1000 cycles 0.5 C. were also found have maintained attenuation They had 643 120 0.2 under high sulfur loading 4.0 mg cm–2. This work provides feasible concept preparation host materials high-performance LSBs.

Abstract Lithium‐sulfur batteries (LiSBs) with high energy density still face challenges on sluggish conversion kinetics, severe shuttle effects of lithium polysulfides (LiPSs), and low blocking feature ordinary separators to LiPSs. To tackle these, a novel double‐layer strategy functionalize is proposed, which consists Co atomically dispersed CoN 4 decorated Ketjen black (Co/CoN @KB) layer an ultrathin 2D Ti 3 C 2 T x MXene layer. The theoretical calculations experimental results jointly demonstrate metallic sites provide efficient adsorption catalytic capability for long‐chain LiPSs, while active facilitate the absorption short‐chain LiPSs promote Li S. stacking serves as microscopic barrier further physically block chemically anchor leaked from pores gaps Co/CoN @KB layer, thus preserving within anchoring‐conversion reaction interfaces balance accumulation “dead S” Consequently, ultralight loading @KB‐MXene, LiSBs exhibit amazing electrochemical performance even under sulfur lean electrolyte, outperforming lithium‐selenium (LiSeBs) can also be achieved. This work exploits universal effective functionalized separator regulate equilibrium adsorption‐catalytic interface, enabling high‐energy long‐cycle LiSBs/LiSeBs.

The severe shuttle effect of polysulfides (LiPSs) and the slow liquid–solid phase conversion are main obstacles hindering practical application lithium–sulfur (Li–S) batteries. Separator modification with a high-activity catalyst can boost LiPSs suppress their effect. In this work, multi-heterostructured MXene/NiS2/Co3S4 rich S-vacancies was constructed facilely hydrothermal high-temperature annealing strategy for separator modification. MXene sheet not only provides physical barrier but also ensures high conductivity adsorption capacity catalyst; dual active centers NiS2 Co3S4 catalyze conversion. addition, vacancies heterostructures modulate electronic structure catalyst, improve its intrinsic activity, reduce reaction barrier, thus facilitating ion/electron transport inhibiting Benefiting from these advantages, Li–S battery modified exhibits exciting discharge capacities (1495.4 mAh g–1 at 0.1C 549.0 6C) an excellent ultra-long cycle life (average decay rate 0.026% 2000 cycles 2C); sulfur loading 10.0 mg cm–2, operates nearly 80 0.2C, giving retention 75.76%.

Abstract Promoting the sulfur reduction reaction (SRR) and evolution (SER) kinetics is crucial for practical lithium–sulfur batteries. However, electrode will be passivated by insulated Li 2 S if blindly accelerated SRR kinetics, meanwhile, high activation energy of lead to premature oxidation (SER), achieving limited catalyst. Here, a nano‐nickel nitrogen‐doped carbon gel material (CG/Ni) induces instantaneous nucleation, further endows fast ion/electron transfer, resulting porous 3D growth instead single lateral growth. Therefore, CG/Ni avoids being passivated, accelerating kinetics. Meanwhile, decreases delithiation barrier, thus, facilitating dissociation. Both experiments theory calculation prove that achieves efficient bidirectional catalysis. Consequently, cathode delivers low‐capacity decay ratio 0.047% per cycle 900 cycles at 5 C. This work unlocks catalyst provide new insight high‐efficiency

Lithium–sulfur (Li-S) batteries are recognized as a promising alternative in the energy storage domain due to their high theoretical density, environmental friendliness, and cost-effectiveness. However, challenges such polysulfide dissolution, low conductivity of sulfur, limited cycling stability hinder widespread application. To address these issues, incorporation heterostructured metallic substrates into Li-S has emerged pivotal strategy, enhancing electrochemical performance by facilitating better adsorption catalysis. This review delineates modifications made cathode separator through heterostructures. We categorize heterostructures three classifications: single metals metal compounds, MXene materials paired with formed entirely compounds. Each category is systematically examined for its contributions behavior efficiency batteries. The evaluated both contexts, revealing significant improvements lithium-ion retention. Our findings suggest that strategic design can not only mitigate inherent limitations but also pave way development high-performance systems.
