Lithium in anodes and cathodes of aluminium electrolysis cells

Lithium salt additions to the electrolyte bring substantial well-known advantages to aluminium electrolysis. There are several ways to add lithium salts to the electrolyte in order to keep the lithium level constant. One such way is to mix lithium carbonate with green anode paste. This paper discusses the catalytic effects of lithium carbonate in anodes and the influence on potlife of lithium fluoride in the electrolyte.
