Abstract
The present invention relates to a secondary battery separator, and a manufacturing method therefor. The secondary battery separator according to the present invention comprises an organic/inorganic composite porous layer for improving thermal resistance and physical strength, and since the organic/inorganic composite porous layer uses polymer particles as a binder, the secondary battery separator, compared with a separator using a solvent-type binder resin using organic solvents, exhibits excellent permeability.
