description A novel wound electrode assembly for a lithium oxyhalide electrochemical cell is described. The electrode assembly comprises an elongate cathode of an electrochemically non-active but electrically conductive carbonaceous material disposed between an inner elongate portion and an outer elongate portion of a unitary lithium anode. That way, lithium faces the entire length of the opposed major sides of the cathode. This inner anode portion/cathode/outer anode portion configuration is rolled into a wound-shaped electrode assembly that is housed inside a cylindrically-shaped casing. A cylindrically-shaped sheet-type spring centered in the electrode assembly presses outwardly to limit axial movement of the electrode assembly. In one embodiment, all the non-active components, except for the cathode current collector which is nickel, are made of stainless-steel. This provides the cell with a low magnetic signature without adversely affecting the cell's high-rate capability.
