Patent ID: 7983021

Claim:
An electrochemical double-layer capacitor comprising (a) a first electrode having a first longitudinal axis, a first body having a thickness, and a plurality of first fingers extending therefrom the first body in a first direction, which is substantially parallel to the first longitudinal axis; (b) a second electrode having a second longitudinal axis, which is substantially parallel to the first longitudinal axis, a second body having a thickness, and a plurality of second fingers extending therefrom the second body in the first direction; and (c) an electrolyte distributed between at least a portion of the first and second bodies; wherein the first and second bodies are positioned in an interlaminated fashion and are separated by at least one non-conductive layer such that the first and second bodies are not in direct electrical contact, wherein the interlaminated first and second bodies are substantially coiled about the first longitudinal axis, wherein the first body and the first fingers of the first electrode are formed from a single first sheet of electrode material, and the second body and the second fingers of the second electrode are formed from a single second sheet of electrode material; wherein at least a portion of the first or second fingers have a thickness greater than at least one of the first or second body thickness; wherein the plurality of first fingers form a first tabbed portion that defines a first predetermined three dimensional pattern, and the plurality of second fingers form a second tabbed portion that defines a second predetermined three dimensional pattern, which is spaced therefrom the first tabbed portion, and wherein the first predetermined three dimensional pattern includes a plurality of straight fingers and a plurality of curved fingers that are curved around the first longitudinal axis, and the second predetermined three dimensional pattern includes a plurality of straight fingers and a plurality of curved fingers that are curved around the second longitudinal axis.
