The present invention relates to a method for manufacturing a secondary pouch-type lithium cell. The method includes a process of charging and discharging an electrode assembly in a pouch. The process also includes a degassing process of removing the gas generated in the pouch in a vacuum and a sealing/venting process of sealing the opening of the pouch and releasing the vacuum at the same time after the degassing process. The present invention can prevent the deformation and weakening of a sealed surface by sealing the opening of the pouch while releasing the vacuum. |
