Supercapacitors

Supercapacitors

Supercapacitors are the next step to closing the gap between batteries (high energy density and low power density) and traditional capacitors (high power density but low energy density). Our group has developed a novel chip scale functionalized carbon nanotube based supercapacitor architecture. Current research for this project focuses on optimization of electrolyte and electrode interactions through multiple designed experiments. We are currently evaluating parameters such as CNT density, functionalization, and electrolyte and their effects on gravimetric and volumetric energy density, capacitance, and lifetime.
