Apparatus for degassing battery cell

An apparatus for degassing a battery cell, comprising:

• a gas suction portion providing negative pressure;
• a first tubular member connected to the gas suction portion, and having at least one suction port formed in a form of a through hole a radial direction of the first tubular member;
• a second tubular member connected to the gas suction portion, and provided to be coupled to the first tubular member;
• and
• a hemispherical cover coupled to the first tubular member and the second tubular member, respectively,
• wherein the hemispherical cover comprises a first cover coupled to the first tubular member and a second cover coupled to the second tubular member,
• wherein, when the first tubular member and the second tubular member are coupled, the first cover and the second cover are disposed such that openings face each other, and the suction port is disposed between the first cover and the second cover,
• wherein the first tubular member penetrates through a gas chamber of the battery cell and is coupled to the second tubular member, and
• wherein, when the first tubular member penetrates through the gas chamber and is coupled to the second tubular member, the suction port is disposed inside the gas chamber.
