摘要

封面展示了一种轻质的、静电纺的纳米纤维“中间层”如何填充纳米TiO2颗粒，作为一种有效的吸附剂，拦截通常来回穿梭并导致容量损失的麻烦的锂多硫化物。通过在硫阴极和分离器之间滑动这种中间层，电池在100次循环后的容量保持率提高了50%以上，而电池的添加量都不到2 wt%。更多信息可以在A. y r m及其同事的研究文章中找到（DOI: 10.1002/cphc.202401136）。

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).

期刊介绍： ChemPhysChem is one of the leading chemistry/physics interdisciplinary journals (ISI Impact Factor 2018: 3.077) for physical chemistry and chemical physics. It is published on behalf of Chemistry Europe, an association of 16 European chemical societies. ChemPhysChem is an international source for important primary and critical secondary information across the whole field of physical chemistry and chemical physics. It integrates this wide and flourishing field ranging from Solid State and Soft-Matter Research, Electro- and Photochemistry, Femtochemistry and Nanotechnology, Complex Systems, Single-Molecule Research, Clusters and Colloids, Catalysis and Surface Science, Biophysics and Physical Biochemistry, Atmospheric and Environmental Chemistry, and many more topics. ChemPhysChem is peer-reviewed.
