Abstract
In a sodium sulphur cell or other electrochemical cell or energy conversion device in which beta-alumina is used as a solid electrolyte in contact with liquid sodium, improved wetting of the electrolyte by the sodium is obtained by coating the electrolyte, on the surface in contact with the sodium, with a metal, such as lead or bismuth, which will form an alloy with sodium. Conveniently the electrolyte is coated with an aqueous solution of lead acetate, dried and the lead acetate decomposed by heating to leave a lead coating.
