Abstract

PURPOSE: To produce metallic lithium with high current efficiency by electrolyzing a mixed salt of a specific compsn. consisting of lithium chloride and potassium chloride at a fused state.
CONSTITUTION: A mixed salt consisting of 42W52wt% of lithium chloride and 58W 48wt% of potassium chloride is charged into cell 21 and heated by heater 35 to form a fused salt of 380W500°C. Next electrolysis is carried out at a voltage of 4W12V and a current density of 50W300a/dm2. At this time, an electric conductive solid electrolyte such as lithium sulfate, lithium-β-alumina or lithium aluminum silicate is used as diaphragm 27 dividing cathode 29 and anode 23. Metallic lithium formed at cathode portion 29 has lower specific gravity than that of the raw material fused salt, so it floats, moves along the ceiling portion of float control element 32, and gathers at recovery portion 33. Argon gas is introduced into portion 33 to prevent oxidation. By this method metallic lithium is obtd. with electrolytic efficiency of about 98%.
