Self-Catalyzed Exothermic Binder Enables Ultrafast Processing and Migration-Resistant Binder Networks for High-Performance Lithium Battery Cathodes.

ABSTRACT: Scalable manufacturing of high-performance cathodes is crucial for next-generation lithium-ion batteries (LIBs). However, conventional binders such as polyvinylidene fluoride (PVDF) require prolonged drying, which slows electrode production and induces binder migration. Herein, we report a self-catalyzed exothermic resin (ExoR) binder that undergoes rapid, thermally triggered polymerization, completing network cross-linking within 3 min while consuming 70% less drying energy than PVDF. Thermal and microstructural analyses confirm rapid ExoR polymerization and complete solvent removal, while revealing a uniform binder distribution and a continuous carbon-binder domain. This architecture lowers interfacial resistance and restrains polarization, producing an enhanced electrochemical response.
