    摘要: A pouch molding apparatus and method involves deforming a pouch so that a larger amount of clearance is secured to increase the capacity of the pouch, thereby improving the pouch molding process to increase the depth and capacity of a pouch cup part. The pouch molding apparatus includes a die and a punch. The die has a die groove recessed therein in a shape configured to mold a pouch. The punch is disposed above the die groove, wherein the punch includes a body part configured to be inserted into the die groove together with a pouch film disposed between the die and the punch, and pressing parts are provided on opposite sides of the body part to press the pouch film toward an inner surface of the die groove.

    摘要: A device for inspecting a welded state between a tab, which protrudes from a plurality of electrodes stacked with a separator therebetween, and a lead welded to the tab. The device for inspecting a welded state may include a pair of tab probes, which are in contact with the tab and spaced apart from each other in a width direction of the tab, and a pair of lead probes which are in contact with the lead and spaced apart from each other in a width direction of the lead. Related methods for inspecting the welded state between a tab and a lead thereby are provided.

    摘要: 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.
