Abstract
The carbon nanotube (CNT) was added into polarizable electrode instead of the acetylene black (AB) as conducting material of the coiled EDLCs. The capacitance of the EDLCs with addition of the CNTs or the ABs are almost same value.The series resistance of CNT-added EDLCs is lower than that of AB by 30[%]. Therefore, it is effective to add the CNTs into polarizable electrode as conducting material of the coiled EDLCs.
