Abstract
(EN)
The present invention relates to a method for manufacturing a secondary battery, and to a secondary battery. The method for manufacturing a secondary battery according to the present invention comprises: an accommodation step of accommodating an electrode assembly in an accommodation portion of a battery case; a vent membrane mounting step of mounting a vent membrane on a discharge hole passing through the inside and outside of the battery case; and a case sealing step of sealing the battery case, wherein the vent membrane allows only gas to pass through the discharge hole of the battery case and blocks the passage of liquid.
