Summary: Lithium-sulfur (Li-S) batteries are promising as new-generation energy storage systems due to their high energy density, cost-effectiveness, and eco-friendliness. However, soluble lithium polysulfides (LiPSs) and dendrite growth of metallic Li hinder their practical applications. This review provides a comprehensive summary of strategies for simultaneously inhibiting shuttle behavior and dendrite growth, including the use of host materials for Li-S full cell, modified functional separators, and tailored electrolytes. The review also discusses the Li-S chemistry mechanism, catalyst principles, and advanced characterization technologies.

Summary: An integrated structure of single Fe atom doped core-shell carbon nanoboxes wrapped by self-growing carbon nanotubes is designed in this study. The carbon needles act as highways for electron transport between the hollow cores and shells, while the self-growing carbon nanotubes further wrap and connect the nanobox shells. The unique structure increases electron transfer and catalytic performance, making it a promising strategy for the development of single atom catalysts.

Summary: A confined self-reduction synthetic route is developed for preparing nanocomposites using diverse metal ions (Mn2+, Co2+, Ni2+, and Zn2+)-introduced Al-MIL-96 as precursors. The nanocomposite derived from Ni2+-introduced Al-MIL-96 contains a hardness unit, amorphous aluminum oxide framework, to restrain volumetric expansion, and a softness unit, Ni nanocrystals, to improve catalytic activity. The study provides a new perspective for designing nanocomposites with hardness units and softness units as sulfur or other catalyst hosts.

Summary: The researchers prepared multifunctional self-supporting hyphae carbon nanobelt (HCNB) as hosts by carbonization of hyphae balls of Rhizopus in order to increase the sulfur loading of the cathode without sacrificing reaction kinetics. Trace platinum (Pt) nanoparticles were introduced into HCNBs (PtHCNBs) by ion-beam sputtering deposition, which regulated the local electronic states of heteroatoms in HCNBs. Electrochemical kinetics investigation combined with operando Raman measurements revealed the accelerated reaction mechanics of sulfur species. The as-prepared PtHCNB/MWNCT/S cathodes exhibited a stable capacity retention of 77% for 400 cycles at 0.5 C with a sulfur loading of 4.6 mg cm(-2), demonstrating a new strategy to prolong the cycle life of LSBs.

Summary: Designed using density functional theory calculations, single-atomic Co-B2N2 site-imbedded boron and nitrogen co-doped carbon nanotubes (SA-Co/BNC) were able to achieve high sulfur loading, fast kinetic, and long service period Li-S batteries. Experimental results showed that Co-B2N2 atomic sites effectively catalyze the conversion of lithium polysulfide. As a result, the electrodes delivered a specific capacity of 1106 mAh g(-1) at 0.2 C after 100 cycles and exhibited an outstanding cycle performance over 1000 cycles at 1 C with a decay rate of 0.032% per cycle. This study offers a new strategy for achieving high-performance Li-S batteries through the combination of nanocarriers and single-atomic catalysts in novel coordination environments.

Summary: Graphene, a star material with attractive properties, has witnessed rapid development in the past decade, giving rise to a family of derivatives including graphene oxides, reduced graphene oxides, graphene foam, vertical graphene, and other 3D graphene architectures. Although commercialization has been achieved for graphene oxides and reduced graphene oxides, they suffer from low electronic conductivity and defects. On the other hand, high-quality graphene foam and vertical graphene produced through CVD and PECVD have emerged, but their fabrication processes are complex and involve high temperature. Future development should focus on high-end 3D graphene derivatives with high electronic conductivity and few defects, requiring the development of new facile preparation methods.

Summary: A versatile route to prepare multi-functional nanocomposites with tuable hierarchical structure via ammonium hydroxide induced self-assembly was reported for improving the performance of lithium-sulfur batteries. The as-prepared WS2@NC composite exhibits superior performance due to higher surface area and total pore volume, easier access to electrolyte, better volume change buffering ability, and more prominent shifting and charge compensation from d band of W compared to Co. The density function theory calculation reveals the higher binding energy towards LiPSs and lower energy barrier for Li+ diffusion on the surface of WS2, contributing to enhanced electronic concentration and more hybridization of d-p orbitals in the Fermi level for improved lithium polysulfide interfacial redox and conversion dynamics.
