An apparatus for automatically collecting gas generated in a secondary battery which is being developed as an energy source for vehicle battery cells, mobile devices, power tools, etc., and automatically injecting the gas into an analysis apparatus so that the gas can be analyzed. The automated apparatus includes a plurality of battery holders in which a plurality of secondary batteries are capable of being mounted, respectively, a battery holder tray in which the plurality of battery holders are placed, a collecting unit which moves in the direction perpendicular to the surface of a secondary battery to be analyzed among the plurality of secondary batteries; and a punching unit which moves in the direction perpendicular to the surface of the secondary battery to punch the surface of the secondary battery The battery holder tray is capable of rotating such that the surface of the secondary battery can face the collecting unit.
