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.

Abstract: The fault-tolerant or self-correcting computer system is disclosed. The computer system that is provided with various sets of protections against failures that may be caused by space radiation, for example. Improved reliability of the system is achieved by scrubbing of the components on a regular schedule, rather than waiting for an error to be detected. Thus, errors that may go undetected for an extended period are not allowed to propagate and further damage the system. Three or more processors are provided to operate in parallel, and a controller is provided to receive signals from the processors and, using a voting logic, determines a majority signal value. In this manner, the controller can detect an error when a signal from one of the processors differs from the majority signal. The system is also provided with a scrubbing module for resynchronizing the processors after a predetermined milestone has been reached. The milestone may be a predetermined time interval or any other event that may be defined by a user.

Abstract: A method of making an electrode structure, and a double layer capacitor including the electrode structure, the method includes the steps of: applying a first slurry including conducting carbon powder and a binder to a current collector plate; curing the applied first slurry to form a primary coating; applying a second slurry that includes activated carbon powder, a solvent and a binder to the primary coating; and curing the applied second slurry to form a secondary coating, thereby forming a first electrode. In variations, additional primary and secondary coatings may be formed on both sides of the collector plate.

Abstract: Methods for manufacturing intermittently coated dry electrodes for energy storage devices and energy storage devices including the intermittently coated dry electrodes are disclosed. In one embodiment, the method includes providing a metal layer and providing an electrochemically active free-standing film formed of a dry active material. The method also includes combining the electrochemically active free-standing film and the metal layer to form a combined layer. The method further includes removing a portion of the electrochemically active free-standing film from the combined layer so that the electrochemically active free-standing film is intermittently formed on the metal layer in a longitudinal direction of the metal layer.
