A novel assembly method and sodium/sulfur battery prepared thereby are provided whereby, in a preformed sulfur compartment, the sulfur electrode is prepared in situ, providing for graduated resistance from the beta-alumina electrolyte to the container wall. The method employs providing for a high resistance conductor as a relatively thin sheet adjacent the beta-alumina electrolyte and a conductive sulfur electrolyte extending from the high resistance conductor to the container wall, whereby the electrolyte is composed of sulfur and small carbon fibers. Conveniently, the high resistance film is positioned adjacent the beta-alumina electrolyte and appropriate amounts of the carbon fiber are introduced into the electrolyte chamber, followed by the addition of molten sulfur.
