The pre-baked carbon anode is usually installed in the upper part of the electrolytic cell, and a strong direct current of 60-300ka is passed through the carbon anode and introduced into the electrolyte. The resistivity of the carbon anode is 50-70 μΩ.m, plus the lead and contact resistance, during normal aluminum electrolysis production, the voltage drop on the carbon anode consumed is 300-500mV, which accounts for 10%-15 of the electrolytic cell voltage drop %. A complex electrochemical reaction (anode reaction) that decomposes alumina occurs at the part where the bottom of the carbon anode contacts the molten electrolyte.
