Molecular interpretability of the bulk electrochemical impedance of concentrated electrolytes
Connie J. Fairchild, Stephen J. Cox, Benjamin Rotenberg +1
Electrochemical impedance spectroscopy (EIS) is a widely used technique to understand time-dependent response and relaxation under applied voltage. While these spectra contain a we…
Dynamics of charge fluctuations in nanocapacitors: effects of salt concentration and electrode metallicity from Brownian dynamics
Paul Desmarchelier, Benjamin Rotenberg
Electric double-layer capacitors (EDLCs) rely on the dynamical response of confined electrolytes to store and release charge, yet the interplay between ion transport, electrostatic…
Brownian dynamics simulations of electric double-layer capacitors with tunable metallicity
Paul Desmarchelier, Alexandre P. dos Santos, Yan Levin +1
We introduce an efficient description of electrodes, characterized by their Thomas-Fermi screening length lTF inside the metal, for Brownian dynamics (BD) simulations of capacitors…
Ions at electrochemical interfaces: from explicit to implicit molecular solvent descriptions
Swetha Nair, Guillaume Jeanmairet, Benjamin Rotenberg
We investigate the interplay between electronic screening inside a metal and screening by a polar molecular solvent, focusing on their impact on the charge induced by an ion and th…
On the strength of underscreening
Andreas Härtel, Roland Kjellander
This paper constitutes a presentation of work in progress at a discussion session of the conference Dense ionic fluids Faraday Discussion, 8-10 July 2024, London, and is published…
