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.

A battery can assembly may include the use of insulating adhesive between the can and cover. Because the cover and can are electrically isolated from each other, the respective battery terminals may be directly coupled thereto, eliminating a feed-through to connect electrodes to positive and negative terminals. Such an assembly can eliminate the need for an electrically insulated feed-through. Additionally, welding between the cover and can, which in some cases may be difficult due to shape, size, and or restricted access, may also be eliminated. This can allow for significant simplification of the battery assembly process.
