摘要： Disclosed is a manganese-based lithium secondary battery comprising a cathode containing manganese-based lithium metal oxide, an anode, and an electrolyte, wherein the anode comprises an anode active material in which a Mn scavenger capable of reducing manganese ions on a surface by conducting or semiconducting properties is coated on part or all of anode active material particles. Through the use of the Mn scavenger, manganese ion dissolved from the manganese-based cathode active material into the electrolyte is preferentially deposited on the Mn scavenger coated on the surface of the anode active material particles, such that the dissolved manganese ion is inhibited from being deposited directly on the surface of the anode active material, and a decomposition of the electrolyte with the deposited manganese component is inhibited. Accordingly, the use of the Mn scavenger can provide a manganese-based lithium secondary battery having excellent storage performance.
