Highly conductive V₄C₃T _<i>x</i> MXene-enhanced polyvinyl alcohol hydrogel electrolytes for flexible all-solid-state supercapacitors.

ABSTRACT: Hydrogel electrolytes are an integral part of flexible solid-state supercapacitors. To further improve the low ionic conductivity, large interfacial resistance and poor cycling stability for hydrogel electrolytes, the V₄C₃T _x MXene-enhanced polyvinyl alcohol hydrogel electrolyte was fabricated to enhance its mechanical and electrochemical performance. The high-conductivity V₄C₃T _x MXene (16,465.3 S m^-1) bonding transport network was embedded into the PVA-H₂SO₄ hydrogel electrolyte (PVA- H₂SO₄-V₄C₃T _x MXene). Results indicate that compared to the pure PVA-H₂SO₄ hydrogel electrolyte (105.3 mS cm
