Abstract: An electrochemical cell includes a can and a jelly roll disposed in the can. The jelly roll includes a positive electrode and a negative electrode, wherein positive winding foils protrude from a positive end of the jelly roll and negative winding foils protrude from a negative end of the jelly roll. The positive winding foils are folded in a same direction to overlap each other in a first pattern of recesses and the negative winding foils are folded in a same direction to overlap each other in a second pattern of recesses. A positive disk includes a plurality of leg forms welded into the first pattern of recesses formed in the positive winding foils. A negative disk includes a plurality of leg forms welded into the second pattern of recesses formed in the winding foils. At least one of the positive disk and the negative disk is electrically insulated from the can.

Abstract: A connector utilized to electrically connect together conductive pads disposed on different substrates includes a flexible substrate having a plurality of conductive through-holes therein. A conductive line formed in the flexible substrate extends between at least two of the conductive through-holes. A plurality of contacts is mounted in the conductive through-holes of the flexible substrate. Each contact includes a post connected to a base of a crown-shaped head having a plurality of projections around the periphery of the base that extend away from the base in the direction opposite the post. The post of each contact is soldered into one of the plurality of conductive through-holes. A compression mat positioned on a side of the flexible substrate opposite the crownshaped heads includes a plurality of resilient cylinders that extend away from a resilient base. Each resilient cylinder has a distal end alignable in registration with a distal end of the post of one of the plurality of contacts.
