Abstract
The invention provides a method of preparing a surface of a ceramic solid electrolyte conductor of alkali metal ions for wetting by said alkali metal in molten form. The method comprises doping the ceramic surface with an oxide of a transition metal. Transition metals such as Fe, Ni, Cu, Mn, Co, Cr or Mo have suitable oxides for doping beta-alumina for wetting by sodium.
