The impedance of a charged flat-plate electric double-layer capacitor
Adrian L. Usler, David Fertig, Mathijs Janssen
We calculate the impedance of a flat-plate electric double-layer (EDL) capacitor by means of Finite Element Method simulations of modified Poisson--Nernst--Planck equations. In Nyq…
Basic requirements for potential differences across solid--fluid interfaces
David Fertig, Adrian L. Usler, Mathijs Janssen
At model water--vapor and water--solid interfaces, molecular ordering leads to charge oscillations and, thereby, to a spatially varying electrostatic potential. Atomistic simulatio…
Charging dynamics of electric double layer capacitors including beyond-mean-field electrostatic correlations
David Fertig, Mathijs Janssen
Electric double layer (EDL) formation underlies the functioning of supercapacitors and several other electrochemical technologies. Here, we study how the EDL formation near two fla…
Transmission line circuit and equation for an electrolyte-filled pore of finite length
Mathijs Janssen
I discuss the strong link between the transmission line (TL) equation and the TL circuit model for the charging of an electrolyte-filled pore of finite length. In particular, I sho…
A Blessing and a Curse: How a Supercapacitor's Large Capacitance Causes its Slow Charging
Cheng Lian, Mathijs Janssen, Honglai Liu +1
The development of novel electrolytes and electrodes for supercapacitors is hindered by a gap of several orders of magnitude between experimentally measured and theoretically predi…
Curvature affects electrolyte relaxation: studies of spherical and cylindrical electrodes
Mathijs Janssen
With two minimal models, I study how electrode curvature affects the response of electrolytes to applied electrostatic potentials. For flat electrodes, Bazant et al. [Phys. Rev. E.…
