Scalable manufacturing of leaf‐like <scp>MXene</scp> /Ag <scp>NWs</scp> /cellulose composite paper electrode for all‐solid‐state supercapacitor

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 “vein-like” cellulose filaments silver nanowires (Ag NWs). The produced nanocomposite 25 wt% Ti3C2TX 8 Ag NWs (PMxAg25-8) exhibits (58 843 S m−1) excellent mechanical properties (Tensile of 34 MPa Young's modulus 6 GPa), which arises synergistic effects interactions between three-dimensional interpenetrating frameworks. This framework can further benefit electrochemical performance papers foldable electrode presents capacitance 505 F g−1 only MXene. work paves way fabrication strong multifunctional macro-assembly electronics conventional papermaking process.
