Abstract:
A NaF-rich composite artificial interphase is in-situ generated relying on a simple chemical reaction by regulating methyl 2,2,2-trifluoromethyl ester reactivity, which can promote rapid ion transport and effectively inhibit dendrite growth in carbonate electrolytes. The assembled NaF@Na‖Na3V2(PO4)3 full cell attains a long lifespan of 4000 cycles at 5C with 95% capacity retention, and a high specific capacity of 80.8 mAh g-1 at 30C.
