Tailored nonwoven supported non-flammable quasi-solid electrolyte enables an ultra-stable sodium metal battery

Abstract

An easily scalable approach to developing a nonwoven-supported PVDF-HFP polymer-based quasi-solid-state flexible non-flammable electrolyte shows a conductivity of 1.16 × 10−4 S cm−1 at RT with a transfer number of 0.68. The Na3V2 (PO4)3 (NVP) cathode-based Na metal cell delivers a discharge capacity of 73 mAh g−1 at a 2C rate and shows exceptional capacity retention of 98.4% after 2500 cycles.
