Abstract: The present disclosure relates to a battery cell and a manufacturing method thereof. The battery cell according to one embodiment of the present disclosure includes an electrode assembly including a cathode, an anode and a separator; and a battery case including a sealing portion that houses the electrode assembly and seals an outer periphery of the electrode assembly, wherein the sealing portion includes a first area, and a second area excluding the first area, and wherein the first area is an area where the crystallinity of the battery case is higher than that of the second area.

Abstract: A pouch-type secondary battery includes a sealing part wherein a two-layer pouch-type battery case is heat-sealed in a state of accommodating an electrode assembly, and includes a cover member positioned between a thickness side of an electrode assembly and a pouch-type battery case on at least one of the four thickness sides constituting the thickness of an electrode assembly. The cover member disconnects a separator from an inner coating layer of the pouch and prevents the separator from being adhered to the inner coating layer when forming the sealing part, and thus prevents damage to the inner coating layer due to the movement of the electrode assembly.

Abstract: A pouch molding apparatus includes a die plate, a first stripper, a punch part, and a second stripper. The die plate has a flat plate shape so that a pouch film is seated on an upper portion thereof and has a molding hole having a shape passing through top and bottom surfaces of the die plate. The first stripper is configured to press and fix the pouch film to an upper side of the die plate and has a punch hole at a position at a position corresponding to the molding hole. The punch part is drawn in and out of the punch hole of the first stripper and the molding hole of the die plate to mold the pouch film. The second stripper protrudes from a bottom surface of the first stripper along a circumference of the punch hole in order to press and fix the pouch film.

Abstract: An apparatus for molding a pouch includes: a die assembly with a die; a stripper assembly to press and fix both sides of a pouch film disposed on the die; and a punch assembly with a punch to mold an electrode assembly accommodation part in the pouch film. The stripper assembly includes: a stripper disposed at a punch assembly lower portion to press and fix the pouch film; a stripper driving piece at a punch assembly upper portion to provide force so that the stripper presses the pouch film; and a connection part to connect the stripper driving piece to the stripper to transmit the force. The connection part includes: two or more connection rods coupled to the stripper; a connection bar coupled to the stripper driving piece; and a connection piece to connect one or more of the connection rods to the connection bar to transmit the force.

Abstract: A pouch shaping apparatus includes a support unit configured to allow a laminate sheet to be disposed on an upper surface thereof, a stripper located above the support unit, the stripper configured to be movable upwards and downwards and to press and fix an outer periphery of the laminate sheet disposed on the upper surface of the support unit when being moved downwards, and a punch located above the support unit, the punch configured to be movable upwards and downwards and to form an electrode assembly receiving portion in the laminate sheet while being inserted into a shaping portion located at the center of the support unit when being moved downwards. The support unit includes an upper support and a support plate, and the pouch shaping apparatus includes a core member located between the upper support and the support plate, the core member having a predetermined thickness.

Abstract: The present invention provides a secondary battery, in which an electrode assembly is embedded in a pouch, and a lead electrically connected to the electrode assembly has one side protruding to the outside of the pouch, the secondary battery comprising: the pouch in which the electrode assembly is embedded, and sealing is performed along an edge thereof; the lead having one end connected to the electrode assembly and the other end protruding to the outside of the pouch; and a lead film disposed between the lead and the pouch and adhering to each of the pouch and the lead when the sealing of the pouch is performed, wherein an expansion part expanded by a predetermined length along a longitudinal direction of the lead is formed on the pouch, and the lead film has an area so that the entire expansion part is accommodated therein.

Abstract: A secondary battery includes: an electrode assembly; an electrode lead; a battery case with an accommodation portion for the electrode assembly and a sealing portion sealing the accommodation portion; and a lead film. The sealing portion includes a connection-sealing region connected to the accommodation portion, a front end-sealing region, and a reinforcement-sealing region therebetween. The reinforcement-sealing region includes a compressed surface, provided in the sealing portion between the connection-sealing region and the front end-sealing region and recessed into the sealing portion, and raised surfaces, provided in the sealing portion between the connection-sealing region and the compressed surface and between the front end-sealing region and the compressed surface and each of which is formed thicker than the compressed surface. The battery case has a resin layer, a metal layer, and an insulating layer.
