摘要: Full‐temperature all‐solid‐state flexible symmetrical fiber supercapacitors (FSCs) are assembled by using montmorillonite flake/polyvinyl alcohol organic hydrogel (F‐MMT/PVA OHGE) as the electrolyte and separator and Ti3C2Tx/ANF‐5%(T/A‐5) fiber as the electrode, in which T/A‐5 fiber is prepared by using delaminated Ti3C2Tx nanosheets as assembled units and 5% of aramid nanofiber (ANF) as the functional additive using a wet spinning method in a coagulated bath with 0.5 m FeCl2 solution. The T/A‐5 hybrid fiber exhibits a …
