Layered Cu7.2S4@N-Doped Carbon Hybrid as a Synergistic Trap Catalyst for Polysulfide Conversion in Lithium-Sulfur Batteries.
Lithium-sulfur batteries (LSBs) are a leading next-generation energy storage technology, owing to their high theoretical capacity and energy density. However, the lithium polysulfide (LiPS) shuttle effect and slow redox kinetics limit the cycling stability and rate capability of LSBs. To address this challenge, a layer...
