Electrode Assembly Comprising Anode With Extension Part

Abstract: The present invention relates to an electrode assembly comprising an anode with an extension part and, specifically, to an electrode assembly comprising: a cathode in which a cathode tab protrudes from one outer end part and in which a cathode current collector is coated with a cathode active material; an anode in which an anode tab protrudes from one outer end part, and in which an anode current collector is coated with an anode active material; and a separator positioned between the cathode and the anode, wherein extension parts extending a predetermined length are formed at the edges of the anode, and bent parts, bent at a predetermined angle so as to surround a part of the sides of the cathode, are formed at the edge of the separator.
