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.
