Low temperature lithium production
Abstract
A method and electrolysis cell for producing lithium metal at a low temperature. The method includes combining (i) phenyl trihaloalkyl sulfone and (ii) an inorganic cation bis(perhaloalkylsulfonyl)imide, an inorganic cation bis(halosulfonyl)imide, an inorganic cation bis(perhaloalkylsulfonyl)imidic acid, or an inorganic cation bis(halosulfonyl)imidic acid in a weight ratio of (i) to (ii) about 10:90 to about 60:40 to provide a non-aqueous electrolyte composition. A lithium compound selected from the group consisting of LiOH, Li2O and Li2CO3 is dissolved in the electrolyte composition to provide a soluble lithium doped electrolyte composition. Power is applied to the electrolyte composition to form lithium metal on a cathode of an electrolysis cell. The lithium metal is separated from the cathode has a purity of at least about 95 wt. %.
