METHOD FOR COLLECTING LITHIUM USING AN ELECTROCHEMICAL METHOD, IN WHICH A CYCLIC VOLTAMMETRY METHOD IS APPLIED AFTER LITHIUM MANGANESE OXIDE IS SLUDGED

摘要

PURPOSE: A method for collecting lithium using an electrochemical method is provided to effectively and economically collect the lithium by a simple process.;CONSTITUTION: A method for collecting lithium using an electrochemical method comprises following steps. Raw materials containing lithium manganese oxide, conductors, and binders are put into a stirrer. A solvent is put into the stirrer, and becomes sludge. The sludge is coated on aluminum foil, and dried. The aluminum foil is put into an electrolyzer with an electrode plate and lithium metal, and reaction voltage is confirmed by a cyclic voltammetry method. The electrolyzer is maintained at the reaction voltage, and the lithium is extracted from the surface of the electrode plate.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Start; (BB) End; (S101) Raw material input step; (S103) Stirring step; (S105) Coating step; (S107) Drying step; (S109) Reaction translocation confirming step; (S111) Lithium extraction step; (S113) Lithium separation step
