An international team of researchers has succeeded in a numerical simulation of the interactions that take place at the molecular level within the electrodes of supercapacitors. This is an important advance in the understanding of the energy storage mechanisms and this experience opens prospects for significant improvements of ultracapacitors.
The operation of a supercapacitor is very different from that of an electrochemical battery. Supercapacitors have the ability to store and deliver more power than batteries. They do not operate on the basis of chemical reactions and can charge or discharge very quickly and last up to a million charge-discharge cycles.
