The problem with supercapacitors is that they still have a relatively high cost per Watt-hour of energy storage potential. Depending on the design, which can rely on Carbon/Carbon electrodes, or metal oxide electrodes, material costs can severely hamper the cost/benefit of employing supercapacitors in these power demand situations. In the Carbon/Carbon case, this is primarily due to the use of an expensive, specially prepared, high surface area carbon particulate, or cloth, that can cost US $50-100/kg.<ref name="Ultra">Burke, Andrew. "Ultracapacitors: why, how, and where is the technology." Journal of Power Sources 91(2000): 37-50</ref> Decreasing the cost by a factor of 10 is required in order to increase the market size for supercapacitors.

By using a 6M KOH electrolyte, the carbon aerogel produced using an R/C ratio of 1500 produced the highest capacitance in the experiment with 110.06 F/g at 1 mV/s scan rate.<ref name="Aero" /> When this scan rate was increased, the capacitance dropped off quickly as the ions in the electrolyte were likely unable to diffuse into the pores as quickly as needed.

Over 400 charge/discharge cycles, the specific capacitance remains relatively constant, ensuring good performance over the long run.
