Claim 18:
19. The process of claim 18, wherein the membrane electrolysis cell further comprises:
a fourth ion exchange membrane, the fourth ion exchange membrane being interposed between the thir ion exchange membrane and the anode compartment, wherein the third and the fourth ion exchange membranes define an acid build up compartment interposed between the anode compartment and the salt depletion compartment, the fourth ion exchange membrane being configured to exchange ions received from the anode compartment to an opposed surface of the fourth ion exchange membrane and into the acid build up compartment;
wherein in performing the process:
H+ ions are formed in the anode compartment and the H+ ions are exchanged from the anode compartment to the opposed surface of the fourth ion exchange membrane into the acid build up compartment; and
the H+ ions and the negative salt ions together form the reagent materials used in the lithium recovery process.
