Abstract: A battery module which includes: a battery stack formed by stacking a plurality of battery cells respectively including electrode tabs on each other; a pair of side covers disposed on both sides of the battery stack; a lower cover on which the battery stack is placed so that one side of the plurality of battery cells is in contact therewith; and an upper cover disposed on a side opposite to the lower cover with respect to the battery stack; wherein the pair of side covers and the upper cover are integrally formed, and the lower cover is fastened to at least one of the pair of side covers.

Abstract: Disclosed are a battery cell assembly for a secondary battery, the battery cell assembly for a secondary battery including at least one battery cell; a first frame disposed on one side of the at least one battery cell; and a second frame which is disposed on the other side of the at least one battery cell so as to face the first frame and which is coupled to the first frame so as to protect the edge of the at least one battery cell together with the first frame. The present invention uses a frame type cell support which retains and supports at least one battery cell without separation, thereby providing a battery cell assembly for a secondary battery, namely a sub-battery module receiving body, having improved structural stability and assembly convenience, and a secondary battery including the same.

Abstract: The present invention provides a battery module, which includes a plurality of battery cells with stacked each other which include a cell body configured to house an electrode assembly and electrode tabs drawn out from the cell body, respectively; and a housing unit configured to enclose at least a portion of an outer surface of the plurality of stacked battery cells to house the plurality of stacked battery cells, wherein the housing unit includes a heat sink unit having a refrigerant flow passage formed therein.

Abstract: The present invention provides a battery module including: a battery group including a plurality of battery cells stacked with each other; a cooling plate which is located in contact with one side of the battery group to cool the plurality of battery cells; and a case which is located on the other side of the battery group so as to surround the battery group, wherein the case comprises an upper cover located on the other side of the battery group; and side covers which vertically extend from the upper cover so as to surround side portions of the plurality of battery cells from which electrode tabs protrude.

Abstract: The present invention provides a battery module comprising: a plurality of battery cells of which the horizontal length of a front surface is formed to be longer than the vertical length and which are vertically stacked; a cooling fin which has a first cooling part contacting an upper and lower surface of adjacent battery cells, and a second cooling part extending from both side surfaces of the first cooling part and contacting both side surfaces of the battery cells which are in contact with the first cooling part; and a side cooling fin which has an ground part contacting a side surface of the second cooling part of the cooling fin, and contacting a heat sink located in a lower part.

Abstract: The present invention provides a battery module, which includes: a plurality of battery cells which include electrode tabs, respectively; and one or more bus bars connected to the electrode tabs for electrically connecting the plurality of battery cells with each other, wherein each of the one or more bus bars includes a plate having one or more openings formed therein, and a plurality of adjacent electrode tabs among the electrode tabs are inserted into any one of the one or more openings of the plate to be electrically connected with each other.

Abstract: The present invention provides a method of manufacturing a battery module, which includes: stacking a plurality of battery cells; applying a thermal conductive member to at least a part of one side of the plurality of battery cells; and bring a cooling plate into contact with the one side of the plurality of stacked battery cells after applying the thermal conductive member, wherein the one side of the plurality of battery cells is an adhesion part which is formed by adhering a case to the electrode assembly on one side except for three sides on which a sealing part is formed by adhering the case among circumferential surfaces of the battery cell in a longitudinal direction thereof.

Abstract: Provided is a battery module for a secondary battery. The battery module includes a busbar for a connection of electrode tabs. According to exemplary embodiments of the present disclosure, in a battery module for a secondary battery, a thickness of a welded portion may be reduced while maintaining a total cross-sectional area of a busbar when electrode tabs of each of secondary batteries are connected in series or in parallel by a laser welding. Thus, the battery module may have an enhanced welding quality, and also may have an effect of being applicable to a high-capacity battery or a battery that is used for a long period of time.

Abstract: A battery module may include a plurality of sub-modules arranged in a single direction, a cooling unit contacting one sides of the plurality of sub-modules to cool the plurality of sub-modules, and a heating unit contacting other sides opposing the one sides of the plurality of sub-modules to heat the plurality of sub-modules.

Abstract: Disclosed are a battery cell assembly for a secondary battery, and a secondary battery comprising the same, the battery cell assembly for a secondary battery comprising: at least one battery cell; and a first frame disposed on one side of the at least one battery cell; and a second frame which is disposed on the other side of the at least one battery cell so as to face the first frame and which is coupled to the first frame so as to protect the edge of the at least one battery cell together with the first flume. The present invention uses a frame type cell support which retains and supports at least one battery cell without separation, thereby providing a battery cell assembly for a secondary battery, namely a sub-battery module receiving body, having improved structural stability and assembly convenience, and a secondary battery comprising the same.
