| Abstract Scope |
High-areal-loading LiFePO₄ (LFP) electrodes are essential for developing cost-effective, high-energy-density lithium-ion batteries, but conventional PVDF binders cause mechanical damage, impede electrolyte transport, and raise environmental concerns. In this study, we propose a mechanically reinforced ion-regulating nanofibril (MRIN) binder. The MRIN binder provides excellent mechanical durability and promotes uniform lithium-ion (Li⁺) conductivity, significantly enhancing ion transport and electrochemical performance. LFP electrodes with the MRIN binder exhibit superior rate capability, improved cycling stability, and significantly reduced interfacial resistance compared to conventional PVDF and CMC binders.
In this presentation, we analyze and clarify these enhanced mechanical durability and ion conductivity characteristics through various characterization techniques and multi-scale simulations. We hope this work can broadly contribute to future research on olivine-based thick electrodes. |
