Abstract:The second generation electrocatalysts with little or without lithium salt have been studied inlaboratory. The promising electrocatalysts which can be used on prebaked anodes in Hall-Heroultprocess can reduce anodic overvoltage (ηa) up to 200 mV,and those which can be used onSoderberg anodes can reduce ηa up to 148 mV.Some arguments about the lithium salt-containinganode paste are discussed.
Key words: aluminium electrolysis lithium salt-containing carbon anodes new electrocatalysts
