Abstract: Disclosed is a secondary battery module including: a plurality of unit cells, at least one or more unit cells among the plurality of unit cells being stacked so as to be in surface contact with each other; and an adhesive pad disposed between contact surfaces of the stacked unit cells. The adhesive pad enhances adhesion between the unit cells to prevent electrical sparks or short-circuiting. Therefore, the secondary battery module is stable and reliable in operation performance and electrical properties.

Abstract: Provided is a battery cell including: an electrode assembly including a first electrode part, a second electrode part, and a separation membrane; a first terminal and a second terminal extending in a first direction or a fourth direction which is an opposite direction to the first direction from the first electrode part and the second electrode part, respectively; a first lead tap and a second lead tap connected to the first terminal and the second terminal, respectively; and a case in which the electrode assembly, the first terminal, and the second terminal are accommodated, which is sealed to expose the first lead tap and the second lead tap to the outside, and in which a sealing part sealed by coating a sealing member on circumferential sides joined with each other is formed.

Abstract: Provided are a secondary battery and a secondary battery pack having the same capable of preventing performance degradation by preventing an increase in an interface resistance of an electrode body accommodated in a pouch and capable of improving stability by preventing deformation of the electrode body to thereby prevent a fine short circuit even though the pouch is swelled due to a gas generate at a high temperature, by providing first members for reinforcing rigidity and second members deformed at the high temperature and capable of adhering the electrode body to one side or both sides of the electrode body accommodated and sealed in the pouch.

Abstract: Provided is a battery cell for a secondary battery, and more particularly, a battery cell for a secondary battery basically including an electrode plate, a case, and electrode tabs. According to the battery cell for the secondary battery in the present invention, since a plurality of battery cells are electrically connected to each other only with a structure of the electrode tabs, a separate component for connection of the electrode tabs is not required, such that it is easy to secure a space at the time of manufacturing a battery pack. In addition, the manufacturing process may be simplified by easy assembly of the battery cells. Further, stability and reliability of the battery cells may be secured.

Abstract: Provided are an apparatus and a method for sealing a pouch-type battery. The apparatus for sealing a pouch-type battery includes sealing tools disposed above and below a sealing part of a pouch, respectively, wherein the sealing tools are disposed so that the sealing part is sealed while having a thickness difference. As described above, the sealing part is sealed while having the thickness difference, thereby making it possible to prevent a phenomenon that the sealing part made of polypropylene, or the like, is pushed into the pouch.
