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.

Claims

1. A device comprising:

an electronic structure;

a supercapacitor structure, the supercapacitor structure comprising one or more layers of supercapacitors, wherein the supercapacitor structure comprise a sheet structure configured and sized to overlie at least a portion of the electronic structure to, in part, facilitate electromagnetic shielding of the electronic structure;

wherein the electronic structure comprises a battery for supplying power to one or more components of an electronic assembly; and

wherein the sheet structure comprises a flexible sheet structure configured and sized to at least partially overlie opposing surfaces of the battery, the main surface of the battery being one surface of the opposing surfaces of the battery.

2. The device of claim 1, further comprising one or more contact tabs, the one or more contact tabs electrically contacting and extending outwards from the supercapacitor structure to facilitate electrical connection to the supercapacitor structure, the one or more contact tabs extending out from at least one edge of the flexible sheet structure, and wherein the one or more contact tables comprise a multi-contact tab, the multi-contact tab being configured and sized with multiple contact locations disposed external to the supercapacitor structure.

3. The device of claim 1, wherein the sheet structure is sized and configured to wrap around the electronic structure.

4. The device of claim 3, wherein the supercapacitor structure at least partially overlies opposing surfaces of the electronic structure, and wherein the electronic structure comprises at least one component of an electronic assembly.
