Abstract
A separator including a porous substrate and an inorganic composite layer formed on one surface or both surfaces of the porous substrate, the inorganic composite layer including inorganic particles, a one-dimensional inorganic material, and an organic binder. The dimensions of the inorganic particles and the one-dimensional inorganic material are different, and the one-dimensional inorganic material is included in an amount of 0.1 to 15 parts by weight with respect to 100 parts by weight of the inorganic particles. Also, a method of manufacturing the separator including coating a dispersion liquid containing inorganic particles, a one-dimensional inorganic material, and an organic binder on one surface or both surfaces of a porous substrate and drying the coated porous substrate to form an inorganic composite layer. Further, an electrochemical element including the separator.
