Lithium-Sulfur Battery Cathodes, Polysulfide Conversion and Sulfur Host Materials
This research community focuses on the development of sulfur-based cathodes and electrolyte systems for rechargeable lithium-sulfur batteries, specifically addressing the chemical conversion of sulfur and the stabilization of intermediate polysulfides.
The work centers on engineering porous carbon structures, metal-organic frameworks, and transition metal catalysts to serve as sulfur hosts. A primary objective is accelerating the redox kinetics of polysulfide conversion to improve battery efficiency and cycle life. Researchers frequently investigate the suppression of the "shuttle effect," where soluble polysulfides migrate between electrodes, by modifying separators and designing interfacial architectures. The materials palette includes graphene oxide, carbon nanotubes, and various metal sulfides or oxides, all aimed at creating stable, high-performance electrochemical interfaces for next-generation energy storage.
The community is most heavily concentrated in research tracked for Lithium, where it represents 5.4% of all Lithium papers (12,027 papers), and Sulfur, where it accounts for 5.1% of Sulfur research (13,690 papers). Carbon research also contributes significantly, with 6,421 papers in this community, though this represents a smaller share (0.8%) of total Carbon research.
The community comprises 15,796 papers, with the highest publication volume in Chemical Engineering Journal (594 papers), Journal of Materials Chemistry A (568 papers), and Journal of Power Sources (504 papers).
Recent papers continue to focus on advanced catalytic sites, such as Ni–N centers and dual single-atom configurations, to enhance polysulfide adsorption and conversion. Newer work also explores strain engineering in electrode materials and the specific chemistry of lithium metal anode corrosion within these battery systems.
