Title:
ELECTROCHEMICAL DOUBLE LAYER CAPACITOR HAVING CARBON POWDER ELECTRODES
Document Type and Number:
WIPO Patent Application WO2003102982
Kind Code:
A3
Abstract:
A method of making a double layer capacitor, in accordance with one embodiment, includes coupling a top collector disk (90) to a proximal end of a double layer capacitor electrode assembly (25); electrically coupling a bottom collector disk to a distal end; heating a can (5); inserting the double layer capacitor electrode assembly (25) into the can (5); cooling the can, wherein a peripheral edge of the bottom collector disk is coupled to the can as the diameter of the can is decreased; forming a bead (110) around an exterior of the can; heating a lid (120); placing a concave structure of the lid in juxtaposition with a convex structure on the top collector disk; cooling the lid, wherein the concave structure is coupled to the convex structure as the diameter of the can is decreased; creating a seal between the lid and the can; and placing an electrolyte solution into the electrode assembly.
