Abstract
An electrochemical cell comprising an electrode assembly in which opposite polarity electrodes are wound together in a bi-directional fashion yielding a high energy density cell stack with low internal impedance is described. Each electrodes is constructed having a slot provided into its width at about a midportion thereof. The slots are brought into registry with each other to form a collapsible X-shaped electrode assembly, which is then bi-directionally folded to provide a wound electrode assembly.
