Highlights Porous MXene (p-MC) films with 3D-interconnected ion transmission paths are constructed by NH3-induced in situ etching strategy. The flexible p-MC film electrodes exhibit a superior capacitance of 688.9 F g−1 with a good rate capability. The as-assembled p-MC solid-state flexible supercapacitors reveal superior electrochemical performance (99.7 F g−1 at 1 A g−1) and excellent flexibility.
