Surface Chemistry and Lithium-Ion Exchange in LiMn 2 O 4 for the Electrochemical Selective Extraction of LiCl from Natural Salt Lake Brines

We report on the surface and bulk chemistry of LixMn2O4 (0 ≤ x ≤ 1) spinel oxide electrode for the selective extraction of LiCl from natural salt lake brines using an electrochemical method based on LiMn2O4 (LMO) lithium intercalation electrode and polypyrrole (PPy) reversible chloride electrode.…
