An electrical double layer capacitor is used to compensate for electricity until another source is connected. The electrical double-layer capacitors utilized in energy fluctuation sources are known as energy equalization. Some power plants generate electricity using green energy, which is subject to natural changes.
In supercapacitors, the electrical double layer formed next to a large-area electrode and an electrolyte is effectively used, and hence these devices are technically called electric double-layer capacitors (EDLCs). At this stage, it is worth summarizing the difference between electrochemical (EC) cells and electrochemical capacitors.
It has been reported that the capacitance of electric double layer capacitors is proportional to the ion concentration and 1/thickness of the double-layer and that the ion concentration is affected by the voltage between two electrodes and the polarization of the carbon electrodes.
To achieve an estimation of the double-layer capacitive effects, De Levie assumed straight, cylindrical pores of uniform diameter and a perfectly conducting electrode. The parameter on the x -axis, depends on the depth within the pore, z, the double-layer capacitance, C, and the electrolyte resistance, R, so that (9) τ = (1 / 4) (z 2 RC) Fig. 6.
As a part of this renewed interest in electric double-layer capacitors (EDLCs), researchers began seeking new strategies to synthesize high surface area porous carbon-based materials as electrodes for EDLCs to obtain high specific capacitance and high energy density.
Double layer capacitors are available with capacities of 10 F up to 5000 F, and specific energies around 4.5 Wh/kg (see Table 1). Specific outputs of 800–1200 W kg −1 are sufficient for most technical applications .
