Title:
METHOD OF RECOVERING LITHIUM FROM BITTERN USING ELECTROCHEMICAL METHOD
Document Type and Number:
WIPO Patent Application WO/2014/046432
Kind Code:
A1
Abstract:
The present invention provides a method of recovering lithium from a bittern using an electrochemical method comprising: a step of preparing a bittern (S10); a step of preparing lithium manganese oxide by adding an absorbent into the bittern (S20); a step of forming a slurry by adding the lithium manganese oxide, a conductive agent, a binder and a solvent into a stirrer and stirring (S30); a step of coating the slurry thus formed on an aluminum foil or a copper foil and drying the coated slurry (S40); a step of securing a reaction potential by putting the slurry-coated aluminum foil or copper foil into an electrolytic bath provided with an electrode plate and a lithium metal by using a cyclic voltammetry method (S50); a step of precipitating lithium on the surface of the electrode plate by maintaining the electrolytic bath with the secured reaction potential (S60); and a step of separating the lithium precipitated on the surface of the electrode plate (S70).
