PURPOSE: A method for manufacturing a secondary battery with a plastic-bag is provided to improve sealability of a sealing part and to increase the safety of the secondary battery. CONSTITUTION: A secondary battery is manufactured by sealing an electrode assembly laminated with a positive electrode, a separation film and a negative electrode, in a battery case. A method for manufacturing the secondary battery comprises the steps of: (i) putting an electrode assembly in a plastic bag in which the electrolyte inlet is included; (ii) injecting the electrolyte in the plastic bag through the electrolyte inlet; (iii) sealing the part excluding a degassing side when the plastic bag is installed in a battery case receiving portion; (iv) activating a battery and removing the gas; and (v) sealing the degassing side. |
