Electrode Assembly And Electrochemical Element Including Same
Abstract: The present invention relates to a separator, an electrode assembly, and an electrochemical element including same, and the separator according to one embodiment of the present invention is used in a zigzag stacking-type electrode assembly. The separator includes a porous substrate made of a polymer material, and porous coating layers formed on both surfaces of the porous substrate and containing inorganic particles. With respect to the lengthwise direction of the separator, the thickness (Ts) of the porous substrate gradually decreases from both ends toward a center part, the overall thicknesses (Tc) of the porous coating layers gradually increase toward the center part, and the entire thickness (Ts + Tc) is maintained constant throughout the entire surface of the separator.
