Abstract: An electrode assembly manufacturing apparatus according to an Example of the present invention may comprise: a stack table performing repetitive up-and-down movement; an electrode supply portion supplying an electrode unit comprising a cathode or an anode to the stack table; and a swing portion rotating according to contact with the stack table, wherein the stack table comprises: a support that supports the electrode unit and that does not contact with the swing portion while the stack table is raised or lowered; and a rotating tray coupled to the support and rotating by contacting with the swing portion while the stack table is lowered.

Abstract: The present disclosure relates to an electrode assembly, a battery cell, and a method for manufacturing a battery cell, and provides an electrode assembly capable of preventing breakage of a current collector improving stability of a battery cell.

Abstract: A battery module case according to an embodiment of the present disclosure includes a plurality of end plates spaced apart from each other in a horizontal direction to accommodate a plurality of battery cells, a cover disposed on one surface of each of the plurality of end plates and having at least one hole extending in the horizontal direction formed therein, and a coupling part coupled to one of the plurality of end plates through the at least one hole.

Abstract: Disclosed is a pouch-type secondary battery, including an electrode assembly; a pouch configured to accommodate the electrode assembly inside; and a sealing part formed along a side circumference of the pouch. The sealing part includes a pattern sealing part in at least a portion. The pattern sealing part is provided with two or more bumpy parts protruding in a direction forming an angle of less than 90° with a height direction of the pouch. Also disclosed is a battery module including the pouch-type secondary battery as a unit cell and a device including the battery module as a power source.

Abstract: Provided is a case for a secondary battery accommodating an electrode assembly, including a lower member, an upper member disposed above the lower member, and a sealing part to which the lower member and the upper member are fused to seal the case. The sealing part includes a first sealing part in which an electrode terminal connected to the electrode assembly exists and a second sealing part which is a remaining area except for the first sealing part. The case includes a polymer resin layer formed on an edge of the first sealing part and a reinforcing layer surrounding the polymer resin layer. The case for a secondary battery has improved water resistance, insulation and mechanical properties. Also provided is a secondary battery, a module, and a device including the same.

Abstract: According to an embodiment of the present disclosure, there are provided a pouch-type secondary battery, including an electrode assembly, and a pouch film including an accommodating part in which the electrode assembly is disposed and a sealing part formed by fusion of edges of the accommodating part, wherein the sealing part includes a pattern sealing part on one or more sides among four sides of the pouch-type secondary battery, and the pattern sealing part includes a plurality of sealings provided with one or more discontinuous parts, and a battery module including the pouch-type secondary battery as a unit cell.
