Green-Cap is the brand name of SAMWHA’s Electric Double Layer Capacitor(EDLC).

Electric Double Layer Capacitor(EDLC) is a next generation energy storage device.

What is the Green-Cap ?

Structure of EDLC

Activated carbon electrode

Activated carbon electrode

Collector Tab

Cylindrical Type Green-Cap Prismatic Type Green-Cap

The structure of EDLC is made by both pasting a

electrode onto the aluminum foil, prismatic type in

stacked layer-type, and cylindrical type in wind-type

winded with a separator.

EDLCs store electrical energy using the electric

double layer that is created at the interface between the

electrode surface and the electrolyte.

The electrodes are made of activated carbon, which

has a high surface area per unit volume, further

increasing the capacitor's energy density.

EDLC has feature that is not electrochemical

reaction, whereby rapid electrical charge and

discharge is possible and have longer life cycle.

How EDLC Works

Green-Cap Applications

• Also called module or pack or bank

Serial connection :

Total Voltage = Voltage of each cell X n

Total Capacitance = Capacitance of each cell / n

Total Resistance = Resistance of each cell X n

Parallel connection :

Total Voltage = Voltage of each cell

Total Capacitance = Capacitance of each cell X n

Total Resistance = Resistance of each cell / n

Ex) 2.5V 60F 15mohm 3 pcs in series = 7.5V 20F 45mohm

2.5V 60F 15mohm 3 pcs in parallel = 2.5V 180F 5mohm

• Serial and/or parallel connection of Green-Caps
