Electrodes were fabricated based on activated carbon powder BP-2O and MSP-20, conducting agent such as Super P and the mixed binders of flexible polytetrafluoroethylene (PTFE) and cross-linking dispersion agent of polyvinylpyrrolidone (PVP) to increase mechanical strength.
In the electrode fabrication of unit cell, it was ascertained that electrochemical characteristics were greatly increase with 78 wt.% of BP-20 and MSP-20, 17 wt.% of Super P and 5 wt.% mixed binder (PTFE : PVP = 9 : 1). Also electric conductivity was increased and internal resistance was decreased with addition of conducting agent.
We found that the 2.3V/1,300F grade EDLC would be applied to industrial safety usage such as uninterrupted power supply (UPS) because of the constant DC-ESR by IR drop regardless of discharge current.
