1. A process for recovering Li from a Li source, the process comprising the steps of:
(a) contacting the Li source with an ion exchange resin or an adsorbing agent to remove lithium from the Li source so as to obtain a lithium containing ion exchange resin or adsorbing agent;
(b) contacting the lithium containing ion exchange resin or adsorbing agent with an acid to regenerate the ion exchange resin or adsorbing agent and to produce a salt-containing solution comprising lithium ions and negative salt ions;
(c) receiving, in a membrane electrolysis cell, the salt-containing solution and a gas comprising O2; and
(d) delivering, from the membrane electrolysis cell, recovered Li and/or reagent materials used in the process for recovering Li;
wherein the Li source comprises a lithium containing brine or solution, the salt-containing solution comprises LiCl, the recovered Li comprises LiOH, and the reagent materials used in the lithium recovery process comprise HCl.
