Abstract (en)
[origin: WO2010142580A1] The present invention relates to a cathode bottom (1) for an electrolytic cell for producing aluminum, comprising a material (3), which can be arranged on at least one cathode block (7), characterized in that the material (3) comprises a pre-compressed plate based on expanded graphite. The present invention further relates to a method for producing a cathode bottom (1), comprising the following method steps: providing at least one cathode block (7), arranging a material (3) on at least one surface of the at least one cathode block (7), wherein the material (3) comprises at least one pre-compressed plate based on expanded graphite. The cathode bottom (1) is used in an electrolytic cell for producing aluminum.
