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.
