Abstract
Abstract An electrochemical reserve cell includes a cylindrical housing a concentric arrangement of a liquid cell component container, a metal anode, a porous separator, and a porous carbon element. The metal anode is cylindrical with a spiral slot extending between its ends and is pressed into a perforated anode support cylinder having adjacent edges welded together. The anode and anode support structure are interlocked together.
