The charging includes: charging a supercapacitor by applying a constant charge to the supercapacitor; and controlling termination of the constant charging of the supercapacitor. In one approach, the controlling termination includes dynamically determining, during the charging, a remaining charge time for the constant charging to substantially fully charge the supercapacitor; and allowing the charging to continue for the remaining charge time, and based on expiration of the remaining charge time, terminating the charging.

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.

A fractal microstructure which includes multi-walled carbon nanotubes suited for customizable volumetric energy and power densities. Electrode monoliths can be formed from a variety of process steps including some or all of RF polymerization, RF coalescence and ripening at intersections, and multi-walled carbon nanotube cross-linking. The resulting nanocomposite is capable of performing all five functions of an electrode while at the same time offering robust mechanical strength and significantly improved energy storage capabilities through, among other things, intra- and inter-particle interlocking.
