Abstract

Binder-free MXene films comprising Ti₃C₂T_x nanoflakes in a face-to-face fashion, achieved by a simple dropping-mild baking approach, exhibit high gravimetric capacitances up to 499 F g⁻¹ with excellent cyclability and rate performances. The entire electrode system including Ni-foam and MXene film shows volumetric capacitances in the range of 84–226 F cm⁻³ depending on the loadings of MXene as active material.
