## Description

- description: Ultrathin MXene-based films exhibit superiorconductivity and high capacitance,
    showing promise as electro-des for flexible supercapacitors. This work describes
    a simplemethod to enhance the performance of MXene-based super-capacitors by expanding
    and stabilizing the interlayer spacebetween MXene flakes while controlling the
    functional groups toimprove the conductivity. Ti3C2Tx MXene flakes are treatedwith
    bacterial cellulose (BC) and NaOH to form a compositeMXene/BC (A-M/BC) electrode
    with a microporous interlayerand high surface area (62.47 m2 g−1). Annealing the
    films at lowtemperature partially carbonizes BC, increasing the overallelectrical
    conductivity of the films. Improvement in conductivity is also attributed to the
    reduction of −F, −Cl, and −OHfunctional groups, leaving −Na and −O functional
    groups on the surface. As a result, the A-M/BC electrode demonstrates acapacitance
    of 594 F g−1 at a current density of 1 A g−1 in 3 M H2SO4, which represents a
    ∼2× increase over similarlyprocessed films without BC (309 F g−1) or pure MXene
    (298 F g−1). The corresponding device has an energy density of 9.63Wh kg−1 at
    a power density of 250 W kg−1. BC is inexpensive and enhances the overall performance
    of MXene-based filmelectrodes in electronic devices. This method underscores the
    importance of functional group regulation in enhancing MXene-based materials for
    energy storage.
