    Abstract: A multi-porous separation film for a secondary battery is provided to ensure excellent thermal stability and tensile strength and to impart high output due to excellent impregnation property to the electrolyte. A manufacturing method of a multi-porous separation film for a secondary battery with high power output and thermal stability comprises (a) a non-solvent addition step for adding a non-solvent to a poly [(vinylidene fluoride)-co-(hexafluoropropylene)] (PVDF-HFP) and heat-dispersing an additive at 35~45 °C, (b) an inorganic additive addition step for adding SiO2 or Al2O3 as a inorganic additive to the product of the step (a) and heat-dispersing the additive at 35~45 to obtain a coating composition in a slurry form, (c) a coating step for bar-coating one side or both sides of the film with a coating composition of a slurry form with a thickness of 60-90 micron, and (d) a washing and drying step for coagulating the coated porous separation film with water at 20~30 °C, washing the coagulated separation film with an alcohol, and drying the washed separation film in a drying oven of 65~75 °C. The non-solvent is selected from the group consisting of ethanol, 1- propanol, 2- butanol, isobutanol, 3- pentanol, dodecanol, N-methyl-2-pyrrolidinone(NMP) and dimethylformamide(DMF).
