Abstract: An electric double-layer ultracapacitor configured to maintain desired operation at an operating voltage of three volts, where the capacitor includes a housing component, a first and a second current collector, a positive and a negative electrode electrically coupled to one of the first and second current collectors, and a separator positioned between the positive and the negative electrode. At least one of the positive electrode and the negative electrode can include a treated carbon material, where the treated carbon material includes a reduction in a number of hydrogen-containing functional groups, nitrogen-containing functional groups and/or oxygen-containing functional groups.

Abstract: Apparatuses and methods for forming an electrode film mixture are described. An apparatus for forming an electrode film mixture can have a first source including a solution comprising a polymer, for example, polytetrafluoroethylene and a critical or supercritical fluid, for example, supercritical carbon dioxide, a second source including a second component of the electrode film mixture, a mixer configured to receive the solution and the second component and to form a slurry comprising the solution and the second component. The apparatus can include a decompressor configured to receive the slurry and decompress the slurry to vaporize the critical or supercritical fluid and precipitate dry polymer.

Abstract: An energy storage device can have a first graphite film, a second graphite film and an electrode divider ring between the first graphite film and the second graphite film, forming a sealed enclosure. The energy storage device may be compatible with an aqueous electrolyte or a non-aqueous electrolyte. A method of forming an energy storage device can include providing an electrode divider ring, a first graphite film and a second graphite film. The method can include pressing a first edge of the electrode divider ring into a surface of the first graphite film, and pressing a second opposing edge of the electrode divider ring into a surface of the second graphite film to form a sealed enclosure. The sealed enclosure may have as opposing surfaces the surface of the first graphite film and the surface of the second graphite film.
