摘要： 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.

摘要： 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.
