Electrode Assembly And Secondary Battery Comprising Same

Abstract: Provided are an electrode assembly and a secondary battery comprising same, the electrode assembly comprising: a positive electrode; a negative electrode; and a separator provided between the positive electrode and the negative electrode, wherein the wet adhesive strength of the separator with respect to the negative electrode is 1.5 gf/20 mm to 15 gf/20 mm. When the wet adhesive strength of the separator with respect to the negative electrode in the electrode assembly satisfies the above range, distortion of the electrode assembly can be effectively prevented before electrolyte impregnation, and bending of the electrode assembly and the secondary battery comprising same following activation can be more effectively suppressed after electrolyte impregnation.
