Abstract
In a sodium-sulfur battery, surfaces of electrically conducting aluminum in contact with sulfur-polysulfide mixtures or potentially subject to contact with such mixtures are protected from the formation of a nonconductive aluminum sulfide coating by a thin coat of electrically-conducting phenolic or poly(arylacetylene) resin which is inert to the sulfur-polysulfide mixture and adheres strongly to the aluminum surface under the conditions of use of the aluminum substrate.
