<p>The present invention relates to a method of manufacturing a two-layered separator for a secondary cell with an improved heat-resisting property and a separator manufactured in accordance to the method, and provides a method of manufacturing a two-layered separator for a secondary cell with an improved heat-resisting property whereby a nozzle block of an electro-spinning unit is divided into two spinning sections in a forward direction thereof; and polymers and inorganic polymers are continuously electro-spun in the spinning sections to manufacture a separator such that a multilayered separator having an improved heat-resisting property can be manufactured, thus the heat-resisting property of the separator, through which a thermal stability thereof can be improved, can be enhanced, and a separator manufactured according to the method. The method comprises the steps of: resolving and electro-spinning a first heat-resisting polymer filled in a first supply unit in an organic solvent to form a first heat-resisting polymer nanofiber; and electro-spinning a solution manufactured by resolving an inorganic polymer filled in a second supply unit in an organic solvent to an upper surface of the first heat-resisting polymer nanofiber to stack an inorganic polymer nanofiber.</p> |
