ABSTRACT:
A sodium-sulfur storage battery having a sealed housing which contains a solid electrolyte incorporating an anodic reactant such as sodium, a cathodic current collector (which may be the housing) extending in a direction generally parallel to the solid electrolyte and cathodic electro-conductive material disposed between and in contact with the solid electrolyte and the cathodic current collector. The cathodic electro-conductive material is impregnated with a cathodic reactant and includes a fiber content, the individual fibers of which have a direction normal to the direction of the cathodic current collector. One suitable material for the cathodic electro-conductive material is a graphite felt and which is impregnated with sodium polysulfide or sulfur.
