TL;DR: This capacitance report reports a method of producing two-dimensional titanium carbide ‘clay’ using a solution of lithium fluoride and hydrochloric acid that offers a much faster route to film production as well as the avoidance of handling hazardous concentrated hydrofluoric acid.

TL;DR: This first report (to the authors' knowledge) on MXene composites of any kind, shows that adding polymer binders/spacers between atomically thin MXenes layers or reinforcing polymers with MXenes results in composite films that have excellent flexibility, good tensile and compressive strengths, and electrical conductivity that can be adjusted over a wide range.

TL;DR: In this article, two-dimensional transition metal carbides exhibit high gravimetric, volumetric, and areal capacitance values at high charcoefficients at high temperature.

TL;DR: Free-standing and flexible sandwich-like MXene/carbon nanotube (CNT) paper, composed of alternating MXene and CNT layers, is fabricated using a simple filtration method, and exhibits high volumetric capacitances, good rate performances, and excellent cycling stability when employed as electrodes in supercapacitors.

TL;DR: Electrode films prepared from a liquid-crystal phase of vertically aligned two-dimensional titanium carbide show electrochemical energy storage that is nearly independent of film thickness, which makes them highly attractive for energy storage applications.
