A supercapacitor stores energy in electrical double layers at electrode/electrolyte interfaces. In molecular modeling of supercapacitors, the structure of electrical double layers is resolved at atomistic scale to determine the capacitance of supercapacitors as a function of electrolyte/electrode properties and operating conditions.


Supercapacitors, also called electrical double-layer capacitors (EDLCs) or ultracapacitors, have attracted significant attention in recent years as a new class of electrical energy storage devices. Supercapacitors have much higher energy density than conventional capacitors and much higher power density than most batteries. As such, they complement these energy storage devices in many applications. Typically, a supercapacitor consists of electrodes, electrolytes, a membrane separator, and current collectors....
