Abstract
In a sodium-sulphur cell, a cathode current collector, which extends into the cathodic region to provide a high conductivity current path, is formed of aluminium with a sheath over the surface of the aluminium or with finned elements secured to the aluminium, the sheath or fins being of a corrosion-resistant metal and being secured to the aluminium by bonding through a protective coating over the surface of the aluminium which serves to protect the aluminium from the cathodic reactant.
