Abstract: Disclosed are an electrochemical catalyst capable of lowering the overpotential of the oxygen evolution reaction (OER) during a water splitting reaction in spite of using inexpensive metals (specifically, base metals) instead of conventional noble metal catalysts in the complex water-splitting reactions that require high overpotential, and a water splitting system using the same.

Abstract: In a method for recovering an active metal of a lithium secondary battery, a sulfuric acid solution is added to a lithium metal composite oxide so as to prepare a sulfated active material solution. A transition metal is extracted from the sulfated active material solution. A lithium precursor is recovered by adding a lithium extracting agent to the solution remaining after the transition metal has been extracted from the sulfated active material solution. In the method, the amount of impurities is reduced, and sulfuric acid and the neutralizing agent can be recycled so that a high-yield lithium precursor recovery is enabled.
