Abstract
⺠Carbon aerogels are KOH-activated at various weight ratios to increase their porosity. ⺠Oxygen and nitrogen functionalities are introduced by different surface treatments. ⺠The gravimetric capacitance is related to N2 adsorption-measured microporosity. ⺠The gravimetric capacitance linearly decreases with increasing particle density. ⺠A volumetric capacitance as high as 123 F cmâ3 is obtained with an O-doped carbon.
