In a sodium sulphur cell, improved protection of a cathode current collector 14 is obtained by isostatically pressing graphite foil 20 or flakes onto the surface of a substrate 21 of the collector, which surface is preferably roughened or coated with an intermediate conductive layer 22 such as a nickel-chromium alloy or a conductive carbide providing a rough surface. <IMAGE> |
