Pouch Cell For Secondary Battery And Manufacturing Method Thereof

Abstract: The present invention relates to: a pouch cell manufacturing method which can reduce the amount of an electrolyte smeared on a sealed portion of a pouch, thereby preventing the sealing quality of the pouch from being degraded by the electrolyte; and a pouch cell which can efficiently discharge internal gas in a pouch to the outside of the pouch. The pouch cell according to the present invention comprises: an electrode assembly; a pouch in which the electrode assembly is accommodated; and a gas discharge tube arranged to extend from the inside to the outside of the pouch, wherein internal gas in the pouch can pass through the gas discharge tube and be discharged to the outside of the pouch.
