Extending the Capability of Supercapacitors Supercapacitors have porous electrodes that can store more charge per volume in electrical double layers than conventional parallel plate capacitors. However, the porous electrodes cause poor performance in filter circuits that eliminate residual alternating current ripple from rectified direct current. Miller et al. (p. 1637) fabricated electrodes with a high surface area for ionic adsorption by growing graphene sheets in the vertical direction off a… Expand
