The separator includes a porous coating layer including a top layer, an intermediate layer, and a bottom layer. An amount of a particle-type binder polymer present in the top layer is larger than an amount of the particle-type binder polymer present in the bottom layer. The porous coating layer also includes a dispersant having a carboxyl group and a glycol group.",
