Abstract: A battery cell manufacturing method comprises scratching a partial region of a plating layer of unit plate material to form a scratch region on the unit plate material; bonding a sacrificial metal sheet to one side of the unit plate material to cover the scratch region; and processing the unit plate material into a cylindrical shape so that the sacrificial metal sheet is exposed to the outside. A battery cell and battery module according to the same are also provided.

Abstract: The present disclosure relates to a battery cell and a battery module comprising the same, and relates, particularly, to a direct water-cooling battery cell and a direct water-cooling battery module comprising the same. According to the present disclosure, the corrosion resistance of the battery cell can be improved by using a sacrificial metal having a higher metal ionization tendency than that of a battery cell case, and the heat of the battery cell can be cooled by using general cooling water for vehicles.

Abstract: A replaceable battery module related to one example of the present invention comprises a battery pack including a groove formed on an outer circumferential surface and a locking member elastically connected to the bottom surface of the groove, and a battery pack mounting part provided with a mounting space, in which the battery pack is detachably mounted, and a locking jaw which is locked and fixed with the locking member so that the position of the battery pack mounted in the mounting space is fixed.

Abstract: The present invention relates to a battery cell and a battery module comprising the same, and relates, particularly, to a direct water-cooling battery cell and a direct water-cooling battery module comprising the same. According to the present invention, the corrosion resistance of the battery cell can be improved by using a sacrificial metal having a higher metal ionization tendency than that of a battery cell case, and the heat of the battery cell can be cooled by using general cooling water for vehicles.

Abstract: A direct water-cooling battery cell is capable of directly cooling heat generated in a battery cell by using non-insulated low-cost general cooling water, rather than insulated. expensive special cooling water. A direct water-cooling battery module comprising a plurality of the direct water-cooling battery cells is also provided.

Abstract: A battery module according to one example of the present invention includes at least one battery cell having a vent part, and a heat dissipation part disposed to face the vent part of the at least one battery cell to dissipate heat from the battery cell. The heat dissipation part includes a heat dissipation film, one side of which is attached to the battery cell to face the vent part of the battery cell, and a heat dissipation case coupled to the other side opposite to one side of the heat dissipation film to form a cooling flow passage.

Abstract: A battery module for preventing chain ignition comprises a plurality of battery cells having vent parts, a cell frame including a cell seating part having a plurality of seating grooves configured to receive the respective vent parts of the plurality of battery cells, and a first adhesive layer disposed between the vent parts of the battery cells and the seating grooves. The first adhesive layer bonds the battery cells to the cell seating part and two adjacent seating grooves of the cell seating part are spaced apart from each other.

Abstract: An ion implantation apparatus includes an ion beam source for generating an ion beam; an implantation energy controller disposed on a path of the ion beam for controlling the ion implantation energy of the ion beam so that an ion beam having a first implantation energy is created for a first period of time and an ion beam having a second implantation energy is created for a second period of time; a beam line for accelerating the ion beam; and an end station for mounting a substrate, into which the ion beam accelerated by the beam line is implanted onto the substrate.

Abstract: Disclosed is a method of managing a search term inputted to a search server. The method includes maintaining a search pocket database for storing a first search term associated with a user, the first search term received from the user when the user is authenticated, receiving at least one second search term from the user when the user is not authenticated, and storing the second search term in a user terminal associated with the user, in a temporary file. The method further includes providing the second search term to the user by referring to the temporary file when the state of the user is changed from the unauthenticated state to the authenticated state, selecting at least one certain search term from the at least one second search term, according to the user's selection, and storing and managing the selected at least one certain search term in the search pocket database together with the first search term.
