Abstract
An electric double-layer capacitor (EDLC) and method for manufacturing thereof. The ELDC includes at least one capacitor cell with two parallel current collectors, two opposite polarity electrodes, a separator, and a rigid dielectric frame. Each electrode is disposed on a respective current collector and impregnated with aqueous electrolyte. The frame is disposed along the perimeter on the surface of a current collector and enclosing the electrodes. The two electrodes of an individual cell are configured asymmetrically, such as being composed of different materials, having different weights, and/or having different thicknesses. The electrode material may include: activated carbon, a transitional metal oxide, a conductive polymer, and/or graphene.
