ELECTROCHEMICAL METHOD OF PRODUCTION OF LITHIUM Russian patent published in 2005 - IPC

FIELD: electrochemistry of aqueous solutions; production of lithium metal.

SUBSTANCE: the invention presents an electrochemical method of production of lithium metal from a water solutions. The method of production of lithium metal from a water - at least of one lithium salt - includes two stages: (1) production of lithium amalgam from a water solution at least of one lithium salt; and (2) electrolysis with use of an anode containing lithium amalgam, a solid electrolyte conducting ions of lithium, a liquid lithium in the capacity of a cathode. At that lithium amalgam acts in the capacity of an anode. The solid electrolyte is tight in respect to helium, and lithium amalgam used in the capacity of the anode is kept in the state of motion. The invention ensures a decrease of power costs and increased output of lithium by a current.

EFFECT: the invention ensures a decrease of power costs and increased output of lithium by a current.
