Abstract: The instant disclosure provides an electrolysis cell, which includes: an anode; a cathode block; and a current collector bar configured to be at least partially disposed adjacent to and in electrical communication with the cathode block, wherein the bar comprises: at least one sidewall; an inner void enclosed by the sidewall; and an expandable material retained in the inner void via the at least one sidewall, wherein the expandable material is configured to exert pressure on the wall of the inner void while the bar is at operating temperature, such that the bar is conformed to the cathode block.

Abstract translation: 本公开提供一种电解池，其包括：阳极; 阴极块 以及集电棒，其被配置为至少部分地布置成与所述阴极块相邻并且与阴极块电连通，其中所述条包括：至少一个侧壁; 由侧壁包围的内部空隙; 以及可膨胀材料，其经由所述至少一个侧壁保持在所述内部空隙中，其中所述可膨胀材料构造成在所述棒处于操作温度的同时在所述内部空隙的壁上施加压力，使得所述棒与所述阴极块 。
