Carbon Anode - an overview ScienceDirect Topics
Welch indicated that anode carbon used for electrodes in aluminum electrolysis cells is disordered as the oxygen bonded to carbon atoms is in a strained five-membered ring, a poorly bonded carbon which is expected to have a higher rate of oxygen desorption from the anode surface. In practice, this has been proven out as more CO is evolved at low current density for poorly baked anodes which ...

Although Soderberg anode may be more energy efficient ...
inorganic chemistry - Why do they use graphite electrodes ...
Graphite anode is used because when carbon react with oxygen liberated at anode it forms $\ce{CO2}$ gas which is a exothermic reaction and maintain the temperature of process and not allow molten aluminum to solidify. Because the density of aluminum in solid form is less dense than cryolite and hence it can't be able to extract from the bottom.

Production - Carbon and Graphite
The cermet materials used in anodes are deemed inert because, unlike carbon, they do not react with oxygen generated by electrolysis of alumina. The cermet materials also have relatively low solubility in the electrolyte. However, inert electrodes are subject to corrosion through several different mechanisms. Aluminum droplets floating or suspended in the molten salt bath may rapidly attack ...
