Engineering a well-connected ion-conduction network and interface chemistry for high-performance PVDF-based polymer-in-salt electrolytes

We incorporate HFA into PVDF-based polymer-in-salt solid electrolyte to form n-AGGs with continuous Li-ion transport path and a LiF-rich SEI, enhancing both ionic conductivity and stability. NCM622‖Li cells stably operate over 600 cycles at 0.2C.
