A cathode current collector for a sodium sulphur cell is formed of a metal substrate, for example of a nickel alloy such as Inconel 600, which is provided with a firmly adherent coating of carbon which is produced by decomposition of a carbon-containing gas in a glow discharge with the substrate heated to a temperature of 200.degree. C. to 1000.degree. C. in an electric field, conveniently a radio frequency field employed for inductively heating the substrate.

Current collector for electrochemical cells and method of making

In a sodium-sulphur cell having a solid electrolyte separating sodium from a cathodic region containing sulphur/polysulphides in a graphite felt, a cathode current collector is formed of an aluminium substrate on which is an interstrate layer of nickel-chromium alloy covered by a coating of titanium oxide or other electronically conductive oxide intrinsically inert to the cathodic reactant.
