Pressure jig of battery cell and gas removal method using the same

Abstract

A battery cell pressure jig of an embodiment of the present invention includes a first pressure block and a second pressure block pressurizing both sides of a battery cell with the battery cell interposed therebetween. The first pressure block and the second pressure block each includes: a flat-type pressure plate that presses the battery cell; a support plate supporting the pressure plate; hinge members provided at the upper edges of the pressure plate and the support plate so that the pressure plate and the support plate are mutually foldable; and an elastic member coupled to the lower end of either the pressure plate or the support plate. The battery cell pressure jig may sequentially press the battery cell from the lower portion to the upper portion.
