  • Large format ultracapacitors and method of assembly
    Patent number: 8102642
    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.
