Electric double layer capacitor (EDLC) is a storage device based on the interfacial interaction between electrode and electrolyte. We have conducted molecular dynamics simulations to study the atomistic origin of storage capacity. Electric double layer structures are studied by changing the electric field applied to the electrolyte. Charge density distribution in the electrolyte phase derived on the basis of molecular dynamics simulation is used to discuss the capacitance-voltage characteristics for different electrolyte species.
