Pre-ophikidwa anode mpweya chipika ndi zofunika komanso zofunika zopangira mu zotayidwa electrolysis makampani. Nthawi zambiri amapangidwa kuchokera ku petroleum coke, asphalt, ndi zida zina zazikulu kudzera munjira zingapo zovuta kupanga. Zopangira kaboni zophikidwa kale za anode zimagwira ntchito yofunika kwambiri pakupanga ma electrolysis a aluminiyamu.
