ELECTRICAL DOUBLE LAYER CAPACITOR AND PRODUCTION OF THE SAME

摘要

An electrical double layer capacitor containing at least one electrical double layer unit which comprises a pair of electrodes separated by a separator and positioned between a pair of collecting plates with an insulating ring being provided with around the periphery of the electrodes, wherein the electrode comprises active carbon fiber fabric carrying active carbon powder thereon, which has stable capacitance and longer discharging time due to small internal resistance.
