TL;DR: Intercalation of hydrazine, and its co-intercalation with N,N-dimethylformamide, resulted in increases of the c-lattice parameters of surface functionalized f-Ti3C2, from 19.5 to 25.48 and 26.8 Å, respectively.

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: New two-dimensional niobium and vanadium carbides have been synthesized by selective etching, at room temperature, of Al from Nb2 AlC and V2AlC, demonstrating good capability to handle high charge-discharge rates.

TL;DR: Overall, the combination of the right electrode materials with a proper electrolyte can successfully increase both the energy stored by the device and its power, but no perfect active material exists and no electrolyte suits every material and every performance goal.
