LITHIUM ION SECONDARY BATTERY AND MANUFACTURING METHOD OF THE SAME

A lithium ion secondary battery includes: an anode including an anode current collector and an anode coating layer coating a region of the anode current collector; a cathode including a cathode current collector, a cathode coating layer coating a region of the cathode current collector, and an inactive coating layer disposed on a surface of a region of the cathode current collector on which the cathode coating layer is not disposed, the inactive coating layer extending from one or more of both end portions of the cathode coating layer toward an end portion of the anode; and a separation membrane arranged between the cathode and the anode.
