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: In this article, the deformation of 2D Ti3C2Tx (MXene) electrode materials at various states-of-charge with a variety of cations (Li, Na, K, Cs, Mg, Ca, Ba, and three tetra-alkylammonium cations) during cycling by electrochemical quartz-crystal admittance was analyzed.

TL;DR: This work provides clear evidence that typical cosmotropic cations are inserted into the MXene interspaces in their partially hydrated form, in contrast to the insertion of chaotropic cations, which effectively dehydrate the MXenes.

TL;DR: Most QCM measurements with electrochemical systems are carried out based on a single (fundamental) frequency and, as such, provided that the resonance bandwidth remains constant, are suitable for only gravimetric sensing.

TL;DR: An in situ hydrodynamic spectroscopic method for porous electrode structure characterization will enable future developments and applications in the fields of battery and supercapacitor research, especially for diagnostics of viscoelastic properties of binders for composite electrodes and probing the micromechanical stability of their internal electrode porous structure and interfaces.
