Abstract
A method of making a double layer capacitor, in accordance with one embodiment, includes coupling a top collector disk to a proximal end of a double layer capacitor electrode assembly; electrically coupling a bottom collector disk to a distal end; heating a can; inserting the double layer capacitor electrode assembly into the can; 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 around an exterior of the can; heating a lid; 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.
