ELETROCHEMICAL DOUBLE-LAYER CAPACITORS:

(in collaboration with R. Ruoff, R. Rogers, Y. Chabal, C. Bielawski, Y. Ishii)

The broad objectives of this project are to advance the fundamental scientific understanding of electrochemical double layer capacitance and thus of ultracapacitor systems composed of a new type of electrode based on chemically modified graphene and (primarily) with ionic liquids as the electrolyte. Almost every form of alternative energy and energy system being implemented today, e.g., wind, solar, hybrid electric and hydrogen fuel cell vehicles, depends on electrical energy storage. Ultracapacitors have the potential for sufficient power density to meet practical pulsed power applications ranging from digital cell phone flash to full regenerative automotive braking to industrial energy harvesting.
