Front Cover: Nanofibrous Interlayers with Ultrafine Decoration of Titanium Oxide to Intercept Lithium Polysulfides in Lithium–Sulfur Batteries (ChemPhysChem 16/2025)

The Front Cover demonstrates how a lightweight, electrospun nanofiber “interlayer” packed with nano TiO₂ particles can act as an effective adsorbant, intercepting troublesome lithium polysulfides that normally shuttle back and forth and cause capacity loss. By slipping this interlayer between the sulfur cathode and separator, the cell saw over 50% higher capacity retention after 100 cycles, all with less than a 2 wt% addition to the cell. More information can be found in the Research Article by A. Yürüm and co-workers (DOI: 10.1002/cphc.202401136).
