The utility model provides an aluminum electrolytic cell. The aluminum electrolytic cell comprises an anode, a cathode assembly, the cathode assembly includes a cathode, cathode block in the block slot and the collector assembly, wherein the collector sub assembly is at least partially placed in the slot; and the axial compression device, the adjacent end of the axial compression device with the current collector and sub assembly suitable for the applied force, to the end of the collector subassembly which through the axial compression device makes the collector sub assembly and slot fit. The compression device provided by the utility model is used for exerting force on the end part of the collector sub assembly to improve the contact, so as to reduce the resistance of the connecting part between the cathode block and the collector subassembly.
