Electrochemical impedance spectroscopy study of the LixMn2O4 interface with natural brine

The LiMn2O4-Polypyrrole electrochemical cell has been shown to extract LiCl from natural brine at low voltage with high selectivity, low energy consumption (5–10 Wh·mol− 1) and good stability. The intercalation/de-intercalation of Li+ ions in LixMn2O4 (0 ≤ x ≤ 1) has been studied by electrochemical...
