With the electronics industry advancing rapidly, the demand for lithium-ion batteries is rising globally, creating a need for a reliable lithium recycling method. One such method is the electrochemical extraction of lithium from a source solution to a recovery solution using an ion exchange membrane and lithiated and de-lithiated LiMn2O4-coated electrodes. Using this method, we have investigated the effects of varying levels of de-lithiation, as well as the method's lithium extraction capability and applicability to a real battery solution. From our testing, both the KCl and the battery solution were found to extract lithium from the source solution, confirming the effectiveness of this electrochemical method.
