Senoo, K

A sodium--sulfur storage battery has 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 electroconductive material disposed between and in contact with the solid electrolyte and the cathodic current collector. The cathodic electroconductive 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 electroconductive material is a graphite felt impregnated with sodium polysulfide or sulfur. 5 figures.
