“…Being pseudocapacitive layered materials, MXenes have demonstrated higher capacitance than carbon-based materials. [710][711][712][713][714][715][716][717][718][719][720] Lukatskaya et al 721 reported that Ti 3 C 2 T x MXene lms possessed a C sp of 210 F g À1 at the scan rate of 10 V s À1 , which was higher than the capacitance achieved with carbonbased SC electrodes. The multi-layered MXene was synthesized by the etching of Ti 3 AlC 2 with HCl/LiF solution.…”

“…Combination MXene with polymers, such as PPy, [13][14][15] polyvinyl alcohol (PVA), 16 and PANI 17,18 could inhibit self-stacking between MXene nanosheets. Hybridization with other carbon materials, including graphene, 19,20 carbon nanotubes, [21][22][23] and carbon nanofibers 24,25 could also improve the electrochemical properties of MXene materials. Cellulose, as an abundance and renewable bioresource, has been found to enhance the overall performance of MXenebased materials.…”

Freestanding films with high strength and conductivity are critical for flexible electronics, such as supercapacitors. Herein, inspired from the natural leaf, a freestanding paper is constructed through fast vacuum filtration by “mesophylls‐like” MXene (Ti3C2TX) nanosheets and “vein‐like” cellulose filaments and silver nanowires (Ag NWs). The produced nanocomposite paper with 25 wt% Ti3C2TX and 8 wt% Ag NWs (PMxAg25‐8) exhibits high conductivity (58 843 S m−1) and excellent mechanical properties (Tensile strength of 34 MPa and Young's modulus of 6 GPa), which arises from the synergistic effects of the interactions between cellulose and MXene and the three‐dimensional interpenetrating frameworks. This interpenetrating framework can further benefit the electrochemical performance of the nanocomposite papers and the foldable paper electrode presents a high capacitance of 505 F g−1 with only 25 wt% MXene. This work paves the way for the fast fabrication of strong and multifunctional MXene macro‐assembly for flexible electronics by conventional papermaking process.

With widespread application of flexible electronic devices, the multifunction for supercapacitors has attracted tremendous attention. Here, developed is a novel multifunctional MXene-based pizeoelectrochemical-type pressure sensor based on highly compressible antiwater supercapacitor. This novel design realizes energy storage and pressure sensing functions simultaneously. The outstanding rate performance is realized by the reasonable design of electron and ion transport channels, originating from strong synergistic bridging interactions between silver nanowires (AgNWs) and MXene. Serving as the electrochemical storage device, even at large 500 mV s–1, the cyclic voltammetry curve of AgNWs/MXene aerogel still maintains nearly rectangular characteristics. For the assembled antiwater symmetric supercapacitor, it records a high specific capacitance of 210.5 F g–1 at 0.5 A g–1, a maximum energy density of 74.7 W h Kg–1 at 400 W Kg–1, and outstanding waterproof cyclic stability of 86.51% in water. Based on elastic AgNWs/MXene aerogel, an antiwater pizeoelectrochemical-type strain sensor is designed, and the device presents stable and sensitive current response while facing external pressure. This study clearly demonstrates that our work promises a new research direction toward the design of next-generation wearable devices that could be used in wirelessly powered wearable devices.
