EDLC Series - Electric Double Layer Capacitors

TDK's Electric Double Layer Capacitor (EDLC) employs a double layer of charged particles formed on activated carbon electrodes in an electrolyte. High capacitance is achieved due to large electrode surface area.

If the current demand from the circuits would be larger than the battery could supply, the line voltage would drop and the system would become unstable. The EDLCs would be able to supply large current for a short period, so that a line voltage-drop would be prevented. Better/faster response to power demand is the feature of EDLCs.
