A cathode element suitable for use in a Hall-Héroult electrolysis cell is described. The element comprises: a cathode block 10 constructed of a carbonaceous material, one (or more) metallic connection bar (s) 13 made of copper or copper alloys. The metallic connection bar 13 is fitted into a groove or bore in direct contact with the carbonaceous material, and where the carbonaceous material can be the carbonaceous material of said cathode block 10, or an intermediate carbonaceous material 17 that is in direct contact with the carbonaceous material of said cathode block 10. The intermediate carbonaceous material may be compressed expanded graphite and/or a cured carbonaceous seal which comprises graphite particles. |
