Abstract
Disclosed is a separator which essentially includes inorganic particles and a binder resin, can be used as a free standing type separator including no separator substrate, such as a polymer resin film, and causes no problem of heat shrinking. In addition, the separator has increased tensile strength by virtue of the improvement of the crystallinity of the binder resin through elongation, and shows a small dimensional change after being impregnated with an electrolyte.
