Abstract (en)
[origin: EP1041177A1] Lithium production from aqueous solution, by lithium amalgam formation and use as a moving anode in an electrolysis cell, is new. Metallic lithium is produced from an aqueous lithium salt solution by forming a lithium amalgam from the solution and using amalgam as a moving anode in an electrolysis cell containing a lithium ion conductive solid electrolyte and a molten lithium cathode. Preferred Features: The lithium amalgam anode is moved by stirring and/or pumping under atmospheric or slightly elevate pressure. The amalgam is produced by chlor-alkali electrolysis.
