Multifunctional Chitosan–Covalent Bonded Multi‐Walled Carbon Nanotubes Composite Binder for Enhanced Electrochemical Performances of Lithium–Sulfur Batteries

Front Cover : Inspired by mussel adhesion, in article 2500155 Liping Zhu, Yan Lu, and co‐workers create a chitosan‐based bio‐binder for lithium‐sulfur batteries. Grafting catechol groups onto chitosan enables strong adhesion and traps polysulfides, countering the “shuttle effect”. Covalent bonds with carbon nanotubes boost both conductivity and mechanical strength. With its eco‐friendly nature, ease of scalable production, and superior electrochemical performance, this innovation provides a transformative solution for high‐energy, sustainable energy storage technologies.
