摘要： 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 watersplitting reactions that require high overpotential, and a water splitting system using the same.

摘要： An electrochemical hybrid catalyst having a structure in which a nitrogen-doped carbon nanostructure (N-C) composite is loaded or decorated with two single atom transition metals indirectly linked adjacent to each other, and thus exhibits high carbon monoxide selectivity and current density at a low overpotential during reduction reaction for converting carbon dioxide into carbon monoxide, and a carbon dioxide conversion system using the same.

摘要： A method for recovering active metals of a lithium secondary battery comprises the steps of: collecting a cathode active material mixture from the cathode of the lithium secondary battery; subjecting the cathode active material mixture to a reducing reaction to prepare a preliminary precursor mixture; forming an aqueous lithium precursor solution from the preliminary precursor mixture; and collecting an aluminum-containing material from the aqueous lithium precursor solution with an aluminum removing resin.

摘要： 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. Provided is a high-yield lithium precursor recovery method in which the amount of impurities is reduced and sulfuric acid and the neutralizing agent can be recycled.

摘要： A method of manufacturing a cathode active material for a lithium secondary battery according to embodiments of the present invention includes performing a first heat treatment on a first mixture of a transition metal precursor and a lithium precursor at a first calcination temperature to obtain a preliminary lithium-transition metal composite oxide particle; and performing a second heat treatment on a second mixture obtained by adding the lithium precursor to the preliminary lithium-transition metal composite oxide particle at a second calcination temperature which is lower than the first calcination temperature to form a lithium-transition metal composite oxide particle.
