Research Progress of Working Electrode in Electrochemical Extraction of Lithium from Brine

Efficient extraction of Li from brine at a low cost is becoming key technology to solve energy and environmental problems. Electrochemical has become research hotspot due its consumption, high selectivity, friendliness. LiMn2O4, LiFePO4, LiNi1/3Co1/3Mn1/3O2 are widely used as cathode materials for the electrochemical but they also have some drawbacks, such small adsorption capacity. In this paper, principle reviewed progress analysis above three working electrode summarized. addition, other rare ions material effect micro-organisms on presented. Next, shortcomings expounded upon direction in prospected. It hoped that paper can provide insights guidance application brine.
