Lithium-Sulfur Battery Cathode Materials and Polysulfide Conversion
This research community focuses on the development of sulfur-based cathodes and host materials to improve the energy density and cycling stability of rechargeable lithium-sulfur batteries.
The work centers on engineering sulfur hosts to manage polysulfide intermediates during charge and discharge. Recurring materials include porous carbon structures, carbon nanotubes, graphene oxide, and metal-organic frameworks. Key methods involve catalytic conversion of polysulfides, redox kinetics optimization, and the design of composite cathodes. Applications are explicitly targeted at high-performance energy storage, with specific attention to suppressing the shuttle effect and enhancing rate capability. The research also explores solid-state electrolytes and interface engineering to stabilize the lithium-sulfur system.
The community is most heavily represented in sulfur research, accounting for 11.7% of all tracked sulfur papers, and in lithium research, where it constitutes 5.5% of the total. Sulfur also contributes the highest raw paper count to this group, with 10,857 papers, while lithium follows with 5,822.
There are 13,170 papers in this community, published primarily in Chemical Engineering Journal, Journal of Materials Chemistry A, and Journal of Power Sources.
Recent work continues to focus on catalytic sites for polysulfide conversion, including nickel-nitrogen centers and dual-defect engineering in transition metal compounds. New studies also examine the impact of strain on redox kinetics and the development of solid-state architectures to mitigate lithium anode corrosion.
