Rosin‐Derived Small‐Molecule Ionic Liquid Hot‐Melt Adhesives With Strong Adhesion Enabled by Noncovalent Interactions

Yabing Tian, Yuling Luo, Jing Wang, Zewei Hu et autres

ABSTRACT Designing small‐molecule adhesives that combine strong yet reversible adhesion remains challenging. Herein, a high‐performance rosin‐derived small‐molecule hot‐melt adhesive ADIm‐TFSI was developed by integrating hydrophobic rosin moieties with ionic groups and polar functionalities. The rigid hydrophobic fused‐ring structure of rosin not only …

Eliminating Interfacial Stress Concentration Enables High‐Energy and High‐Safety Gel Polymer Lithium Metal Pouch Cells

Wenran Wang, Haipeng Zhu, Qiangfeng Zhang, Pei Huang et autres

ABSTRACT Interfacial stress concentration not only degrades electrochemical performance during cycling but also poses critical safety risks under extreme abuse conditions. Upon nail penetration, localized stress accumulation can trigger catastrophic mechanical failure and rapid thermal runaway. Herein, we report a gel polymer …
