Abstract

A system is provided including an electrolysis cell configured to retain a molten electrolyte bath, the bath including at least one bath component, the electrolysis cell including: a bottom, and a sidewall consisting essentially of the at least one bath component; and a feed material including the least one bath component to the molten electrolyte bath such that the at least one bath component is within 30% of saturation, wherein, via the feed material, the sidewall is stable in the molten electrolyte bath.
