Patent ID: 8503161

Claim:
A supercapacitor comprising: (a) a cavity internally coated with a first electrode interconnect metal; (b) a lid coated with a second electrode interconnect metal disposed on a side facing toward said cavity, wherein said lid and said cavity form a hermetic seal; (c) first carbon nanostructures electrically continuous with a portion of said first electrode interconnect metal; (d) second carbon nanostructures electrically continuous with a portion of said second electrode interconnect metal; (e) metal oxide coating on outer surfaces of said first and second carbon nanostructures; (f) an electrolyte within said cavity; (g) a first electrode via in said lid, wherein said first electrode via exposes said first electrode interconnect metal on a border surface of said cavity; (h) a second electrode via in said lid, wherein said second electrode via exposes said second electrode interconnect metal; and (i) a first electrode metal terminal and a second electrode metal terminal each disposed on said lid, wherein said first electrode metal terminal connects through said first electrode via to said first electrode interconnect metal, and wherein said second electrode metal terminal connects through said second electrode via to said second electrode interconnect metal.
