<p>The present invention discloses an electrolytic cell for aluminum electrolysis, comprising a cell body, wherein an anode and a cathode are arranged inside the cell body, the cell body is further filled with an electrolyte, and at least a part of the anode is immersed in the electrolyte; the anode is arranged above the cell body, the cathode is arranged at the bottom of the electrolytic cell and is covered by a certain amount of aluminum liquid, the electrolyte is located between the anode and the cathode and covers the aluminum liquid; and an insulating layer is arranged on the inner sidewall of the cell body and is used for isolating oxygen or the electrolyte from a carbon block. The electrolytic cell for aluminum electrolysis is characterized in that the anode contains the components including Fe, Cu, Ni and Sn, wherein Fe and Cu serve as primary components; and the electrolyte is composed of 30-38wt% of NaF, 49-60wt% of AlF 3 , 1-5wt% of LiF, 1-6wt% of KF and 3-6wt% of Al 2 O 3 , wherein the molar ratio of NaF to AlF 3 is 1.0-1.52. The electrolytic cell can be used for preparing industrial electrolytic aluminum.</p> |
