Electrode models for ionic liquid based capacitors — •Kai Szuttor, Konrad Breitsprecher, and Christian Holm — Institute for Computational Physics, Stuttgart, Germany

We compare different simulation models for ionic liquid based capacitors concerning the electrode model. Therefore molecular dynamics simulations of an explicit graphite model are compared to a plain wall electrode with adapted interaction parameters. Further we compare two simulation approaches with constant potential boundary conditions to constant charged electrodes and the influence of these different methods with regard to the differential capacitance and the layering behavior of the ionic liquid at the electrode.
