Abstract: One embodiment is an EDLC with a capacitor cell that includes two electrodes of opposite polarity aligned in parallel, and a peptide separator disposed between the electrodes. The separator may be a peptide coating on an electrode surface. Another embodiment is an electrode for an electrochemical energy storage device, such as an EDLC, the electrode including graphene and coated with peptide. The peptide may act as a separator for the EDLC. A further embodiment is an electrode for an electrochemical energy storage device, the electrode-unit including: two graphene layers, CNTs, and electrolyte. The graphene layers are arranged separated along a first axis and aligned with parallel surfaces, where at least one graphene layer is coated with peptide. The CNTs are arranged along a second axis orthogonal to the first axis and disposed between the graphene layers. The electrolyte is impregnated within the volume defined between the graphene layers and CNTs.

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, a rigid dielectric frame, and at least one evacuation mechanism. 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 evacuation mechanism removes superfluous fluid material from the capacitor cell interior. The evacuation mechanism may be a compartment in the frame, operative to collect residual electrolyte that seeps out from the electrodes, or a capillary formed within the frame and extending into a portion of the electrode, the capillary composed of a porous hydrophobic material and operative to evacuate discharged gases from the electrodes out of the EDLC.
