Abstract: A Dense Energy Ultra Cell (DEUC), a dielectric energy storage device and methods of fabrication therefor are provided. A DEUC element is fabricated using print technologies that deposit dielectric energy storage layers (406) and insulating layers (404) together being interleaved between electrode layers (403). The dielectric energy storage layers are created from a proprietary solution to enable printing of dielectric energy storage layers with high permittivity and a high internal resistivity to retain charge. The insulating layers (404) can be applied within the dielectric energy storage layers (406) bifurcating the dielectric energy storage layers for increased resistivity. As part of the fabrication process, the material deposition printer can apply multiple print heads each with different inks and materials (1301, 1302) to form composite material (1303) in the printed layers.

Abstract: Supercapacitor structures are provided which include, for example: one or more layers of supercapacitors; and one or more contact tabs. The one or more contact tabs electrically contact and extend outward from the supercapacitor structure to facilitate electrical connection to the supercapacitor structure, and the one or more contact tabs include a multi-contact tab. The multi-contact tab is configured and sized with multiple contact locations which are disposed external to the supercapacitor structure. Various supercapacitor structures are provided, including one supercapacitor structure with a shared C-shaped current collector, and another supercapacitor structure with stacked supercapacitors. One or more additional multi-contact tabs may also extend from the supercapacitor structure(s) and distribute the same or a different capacitor voltage than the multi-contact tab.

Abstract: Disclosed is an aluminum ion capacitor, including a separator, an anode and a cathode, between which the separator is interposed, and an electrolyte contacting the anode and the cathode, wherein the anode contains aluminum, the electrolyte contains aluminum ions, and an electrical double layer is formed at the cathode and intercalation and deintercalation of aluminum ions are performed at the anode. Accordingly, a supercapacitor having increased energy density can be effectively manufactured at lower cost than lithium ion capacitors, and also, the supercapacitor has high material stability and thus is not limited as to electrode configuration, and an electrode configuration that has a low manufacturing cost and is able to increase energy density and power density can be adopted.
