Electrode Assembly And Method For Manufacturing Same

Abstract: The present invention provides an electrode assembly comprising: a separator bent in a zigzag shape, and including a porous polymer substrate, a first porous coating layer formed on one surface of the porous polymer substrate, and a second porous coating layer formed on the other surface of the porous polymer substrate; a negative electrode disposed between first porous coating layers; and a positive electrode disposed between second porous coating layers, wherein the first porous coating layer, which has an adhesive strength with the negative electrode greater than an adhesive strength with the positive electrode, is used such that the electrode-separator adhesive strength deviation on both sides of the separator is reduced, thereby reducing bending.
