Abstract: An electrode assembly for use in a reduction cell for the production of metal such as aluminum. The electrode comprises an electrically conductive carbon electrode block with an electrically conductive metal member connected thereto. At least one solid, conductive metal insert is at least partly received in the carbon electrode block with an interference fit, such that the insert exerts a lateral force on the carbon electrode block. The insert provides an improved electrically conductive connection between the carbon electrode block and the conductive metal member, with reduced resistance. The insert may provide a direct connection between the electrode block and the metal member, or the connection may be provided through a layer of cast iron or other metal element provided between the electrode block and the metal member. The electrode assembly may either comprise an anode or a cathode.
