The method of making a sulfur electrode container construction of a type for containing sulfur in liquid form comprising the steps of forming a sheet of anti-corrosive foil material into a cylindrical body, disposing said body into a cylindrical container of a material which is significantly subject to corrosion by liquid sulfur, disposing said cylindrical body into the container in a manner disposing the outer sidewall of the body in closely spaced relation to the sidewall of the container to form a protective liner within the container while permitting sulfur vapor to pass into the spacing defined between the inner sidewall surface of the container and the outer wall surface of the cylindrical liner to form a coating of sulfides of the container and liner materials in interlocked relation to support the liner from the wall of the container while filling the space therebetween to block liquid sulfur from entering therebetween.
