Methods for lithium metal production direct from litium brine solutions

An apparatus for obtaining lithium metal comprising:

• (A) an extraction chamber;
• (B) a plating chamber;
• wherein the extraction chamber is in fluid communication with the plating chamber;
• wherein the plating chamber comprises a cathode and the extraction chamber comprises an anode.

A system for cathodic electrodeposition of lithium (Li) onto a moving metal foil, the system comprising:

• (A) a containment cell carrying at least a lithium-containing solution;
• (B) a counter electrode extending in the containment cell;
• and
• (C) a working electrode extending in the containment cell,
• wherein the working electrode comprising a metal foil configured to be continuously moved through the lithium-containing solution via a roll-to-roll conveyance system, the counter electrode and the working electrode configured to be charged in such a manner as to drive electrodeposition of lithium onto the metal foil extending through the lithium-containing solution.

A system for cathodic electrodeposition of lithium (Li) onto a metal foil, the system comprising:

• (A) a containment cell;
• (B) a counter electrode extending in the containment cell;
• (C) a working electrode extending in the containment cell, the working electrode comprising a metal foil;
• and
• wherein a cation exchange membrane carried in the containment cell and positioned between the counter electrode and the working electrode, the cation exchange membrane and the containment cell together defining a first chamber and a second chamber, the first chamber carrying the working electrode and configured to contain a lithium-containing organic solution, the second chamber carrying the counter electrode and configured to retain at least one of a lithium-containing aqueous solution or a lithium-containing brine, the counter electrode and the working electrode configured to be charged in such a manner as to drive both lithium ion movement through the cation exchange membrane and electrodeposition of lithium onto the metal foil contacting the lithium-containing organic solution.
