Abstract

Abstract The existence of the oxygen-containing functional groups on MXene surface makes it a potential electrode material in supercapacitor based on a redox mechanism. However, the irreversible stacking of MXenes will lead to an insufficient utilization of these functional groups. To solve this problem, we fabricated a composite electrode comprised of 2D delaminated Ti3C2 sheets (d-Ti3C2) and 3D Ni foam (NF) by electrostatic self-assembly. In this electrode, d-Ti3C2 nanosheets are adsorbed on the surface of 3D Ni foam skeleton structure, eliminating the need for insulative polymer binders. The self-assembly strategy endows d-Ti3C2/NF composites with unique 2D/3D structure which possesses the merits of excellent conductivity, sufficient active sites, high charge transfer efficiency and short ions diffusion path. As a result, the d-Ti3C2/NF composite electrode exhibits a high specific capacitance up to 654 F g−1 at 1 A g−1 and good cycling stability. An asymmetrical supercapacitor with d-Ti3C2/NF composite as a positive electrode, bulk Ti3C2 (b-Ti3C2) as a negative electrode and 6 M KOH as electrolyte, exhibits a maximum energy density of 18.1 Wh kg−1 (at 397.8 W kg−1) and excellent cycling stability (80.6% after 5000 cycles). The results indicate that d-Ti3C2/NF composite is a promising electrode material for practical energy storage devices.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
