Claim 10:
11. An apparatus for one-step purification of lithium compounds, comprising:
an electrolyte compartment for storing a molten electrolyte comprising a lithium salt and an aluminum salt;
an anode comprising metallic aluminum positioned in contact with the molten electrolyte;
a cathode compartment for storing molten lithium;
a solid electrode positioned in contact with the molten lithium;
a solid electrolyte positioned between the electrolyte compartment and the cathode compartment,
wherein the solid electrolyte allows lithium ions, but not any other atoms, to pass through, and comprises a garnet-type oxide comprises Li7-xLa3TaxZr2-xO12 wherein x is from 0.4 to 0.6, wherein the solid electrolyte has a relative density from 97% to 99.9%, and wherein after the purification, the apparatus is configured to increase a lithium concentration in the molten lithium by from 7.2 times to over 1500 times at the molten electrolyte.
