Abstract
In sodium/sulfur batteries, electrical contact is maintained between the sulfur which is nonconductive and an aluminum container or other external electrical conductor, by having electrical contact between the sulfur and conductive carbon fibers and/or mat which contact a molybdenum or chromium coated surface of an aluminum conductor. A terminal portion of the aluminum conductor is uncoated and is employed for making electrical contact to the external conductor. A battery configuration of particular interest has a central .beta.-alumina tube which may serve as the sulfur or sodium container surrounded by sodium or sulfur respectively.
