Abstract (en)
[origin: GB2558936A] The cathode assembly (C) comprises: a cathode body (1) made of a carbonaceous material, and at least one cathode collector bar (3, 3') made of a metallic material. The cathode body (1) being having at least one slot (17, 17'), said slot being provided with side walls (171, 172, 171', 172') parallel to a longitudinal direction (A17, A17') of said slot. The cathode bar being provided with side walls (33, 34), which are in contact with said side walls of said slot. The cathode bar comprises two bar elements (7, 9), each bar element being provided with a main side wall (73, 93) which is in contact with a respective side wall (171, 172) of said slot, as well as a tapered wall (77, 97), the two tapered walls of said bar elements forming a contact line (37) between these two bar elements.
