Abstract: An integrated energy storage unit includes a container and a battery housed within the container. The battery includes a positive battery terminal, a negative battery terminal, and a battery electrolyte. A capacitor is housed within the container, separate from the battery. The capacitor includes a positive capacitor terminal, a negative capacitor terminal, and a capacitor electrolyte. A plurality of connectors electrically couple the battery and the capacitor in parallel. A positive lead is electrically coupled to the positive battery terminal and the positive capacitor terminal. The positive lead extends from the container. A negative lead is electrically coupled to the negative battery terminal and the negative capacitor terminal. The negative lead extends from the container.

Abstract: A capacitor includes a plurality of electrode substrates, with each of the plurality of electrode substrates having a coated portion and an uncoated portion. The coated portion is coated with a coating material that includes a high surface area activated carbon material, a water soluble binder selected from the group consisting of: poly vinyl alcohol, poly acrylic acid, polymethacrylic acid, polyethylene oxide, polyacrylamide, poly-N-isopropylearylamide, poly-N,N-dimethylacrylamide, polyethyleneimine, polyoxyethylene, polyvinylsulfonic acid, poly(2-methoxyethoxyethoxyethylene), butadiene-acrylonitrile, and combinations thereof, and a water soluble thickener. A separator is inserted between adjacent substrates of the plurality of electrode substrates. The capacitor further includes an electrolyte. A method of manufacturing the capacitor is also provided.
