SYSTEM OF RECOVERING LITHIUM PRECURSOR AND METHOD OF RECOVERING LITHIUM PRECURSOR

The invention relates to a method of recovering a lithium precursor from a cathode active material of a lithium secondary battery, the method comprising providing a first electrode to include the active material, and a second electrode. The first electrode and the second electrode are immersed in a first reaction solution in a first reaction vessel and a second reaction solution in a second reaction vessel, respectively. A voltage or a current is applied to the first electrode and the second electrode to recover a lithium precursor from the active material.
