Abstract
An electrical storage device utilizing a pyrazine-based cyanoazacarbon or pyrazine-based cyanoazacarbon polymer as a redox active material which can undergo both oxidation and reduction. The device has an ion selective barrier with a cathode side and an anode side; a cathode compartment which is functionally attached to the cathode side of the ion selective barrier and contains a mixture of pyrazine-based cyanoazacarbons, solvent, and positive ions of pyrazine-based cyanoazacarbons; an anode compartment which is functionally attached to the anode side of the ion selective barrier and contains a mixture of pyrazine-based cyanoazacarbons, solvent, and negative ions of pyrazine-based cyanoazacarbons; a cathode which is electrically connected to the cathode compartment; and an anode which is electrically connected to the anode compartment. In one embodiment, the electrical storage device has an electrolyte reservoir which uses an asymmetric membrane design to transfer electrical charge between an anode section and cathode section. For slow redox, the electrical storage device functions as a rechargeable battery. For rapid redox, the electrical storage device functions as a supercapacitor.
