  • Patent number: 11189434
    Abstract: An electrical energy storage device comprises a housing having a first end, a second end, a first side, and a second side; a first electrode disposed in the housing adjacent the first side; a second electrode disposed in the housing adjacent the second side; and an electrolyte mixture disposed between the first electrode and the second electrode, the electrolyte mixture containing a plurality of ions. In an implementation, a channel disposed in the housing permits ions to flow adjacent to the first end and a barrier in the housing prevents ions from flowing adjacent to the second end. In another implementation, some of the ions are magnetic. In a further implementation, some of the ions have a greater density than other ions. Charging of the electrical energy storage device is enhanced by applying a magnetic field to the electrical energy storage device or rotating the device.

  • Patent number: 11181344
    Abstract: A supercapacitor-like device is described that uses a porous, conductive foam as the electrodes. After the device is charged, an explosive wave front can be used to remove electrolyte from the metal foam. This creates a large net charge on each electrode, which will readily flow through a load placed across the electrodes. The removal of charge can potentially occur on a time scale of microseconds, allowing a supercapacitor to be used in pulsed power applications. The creation of this net charge requires significant energy, meaning this concept may also be suitable for removing kinetic energy from objects.
