<p>The present invention relates to a method for recovering lithium using an electrochemical method. More particularly, the method according to the present invention comprises: putting a raw material made of lithium manganese oxide, a conductive material, and a binder into an agitator; performing agitation for the production of sludge by putting a solvent into the agitator into which the raw material is put through the inputting of the raw material; coating an aluminum foil or a copper foil with the sludge produced through the performing of the agitation; drying the sludge with which the aluminum foil or the copper foil is coated through the coating; evaluating a reaction potential using cyclic voltammetry by putting the aluminum foil or the copper foil, which is coated with the sludge dried through the drying, into an electrolyzer provided with an electrode plate and a lithium metal; maintaining the reaction potential evaluated by means of evaluating the reaction potential for the precipitation of lithium on a surface of the electrode plate; and separating the lithium precipitated on the surface of the electrode plate through the precipitating of the lithium.</p> |
