Abstract
A sulfur electrode container is described which includes a metallic liner in foil form with at least two full windings within an outer casing. The liner is substantially corrosion resistant to liquid sulfur, while the outer casing is readily corroded by liquid sulfur. One method of making a sulfur electrode container includes forming a metallic liner in foil form into at least two full windings within the outer casing. Another method of making a sulfur electrode container includes wrapping a metallic liner in foil form into at least two full windings around a sulfur-carbon plug, after which the plug surrounded by the foil, is positioned within an outer casing.
Claims6
A method of producing a sulfur electrode container which consists essentially of providing an outer metallic casing having opposite open ends readily corroded by liquid sulfur, providing a metallic foil substantially corrosion resistant to liquid sulfur, forming the foil into at least two full windings within said casing producing a self-sealing protective liner in situ in said casing, said liner being contiguous to and coextensive with the inner surface of said casing, and sealing one open end only of the casing with a metallic end cap fitted within and adjacent said open end of said casing, said end cap having an inner surface substantially corrosion resistant to liquid sulfur.
