Self-assembled Ti3C2Tx MXene film with high gravimetric capacitance†
Abstract
Binder-free MXene films comprising Ti3C2Tx nanoflakes in a face-to-face fashion, achieved by a simple dropping-mild baking approach, exhibit high gravimetric capacitances up to 499 F gā1 with excellent cyclability and rate performances. The entire electrode system including Ni-foam and MXene film shows volumetric capacitances in the range of 84ā226 F cmā3 depending on the loadings of MXene as active material.
