An apparatus for mounting a battery cell mounts a battery cell stack to a frame that includes a base cover and a pair of side covers respectively extending from both ends of the base cover. The apparatus includes a support member to support the battery cell stack, a roller member around which a film fixed to the support member is wound, and a film guide member configured to move the film into the frame. When the film guide member moves the film into the frame, the support member and the frame move toward each other, and the battery cell stack is movable along the film to be mounted to the frame.

The present invention relates to an electrode assembly having an external shape fixation frame, and more particularly an electrode assembly including a unit cell including one or more electrodes and one or more separators, wherein the electrode assembly is at least one selected from among a stacked type electrode assembly, a stacked and folded type electrode assembly, and a wound type electrode assembly, and the electrode assembly includes an external shape fixation frame configured to wrap a portion of an outer surface of the electrode assembly, and a lithium secondary battery including the same.

A battery module includes a battery cell stack in which a plurality of battery cells are stacked; a plate-shaped lower plate located under the battery cell stack; a module frame for covering an upper surface and both side surfaces of the battery cell stack; and a thermal conductive resin layer located between the lower plate and the battery cell stack.

The present invention provides a sequential and efficient method of assembling a battery with a desired number of layers while reliably separating positive and negative electrode sides from each other with one or more separator structures. According to the invention, the method of assembling a battery includes stacking one or multiple combinations each comprising a frame and a positive electrode plate to be disposed in a region defined by the frame and one or multiple combinations each comprising a frame and a negative electrode plate to be disposed in a region defined by the frame, once or alternately, such that the positive and adjacent negative electrode plates are separated from each other by a separator structure and the periphery of the separator structure is held between the adjacent frames. The separator structure includes a separator exhibiting hydroxide ion conductivity and water impermeability.

An electrode connecting device for connecting an end of a preceding sheet to an end of a succeeding sheet includes: an arrangement member provided with an arrangement part on which the end of the preceding sheet is located adjacent to or overlapping with the end of the succeeding sheet; and a guide member having a guide bar which is provided movable between a support position to support a side portion of the preceding sheet and a side portion of the succeeding sheet during connecting of the end of the preceding sheet to the end of the succeeding sheet and a retreat position not to interfere with movements of the preceding sheet and the succeeding sheet.

A battery module of the present invention is adaptable to be utilized in various configurations including and not limited to an overlapping battery cell packaging configuration and a vertical stack battery cell packaging configuration used in an automotive and non-automotive applications. The battery module has a plurality of battery heatsink assemblies with the cells disposed therebetween. A plurality of rods extend through the each heatsink assemblies to secure the heatsink assemblies and the cell with one another to form the battery module.

A battery plate having a substrate with opposing surfaces and one or more nonplanar structures and one or more active materials disposed on at least one of the opposing surfaces; wherein the battery plate includes one or more of: i) one or more projections disposed within but do not extend beyond the active material; ii) one or more projections which project beyond the active material and substantially free of the active material or dust formed from the active material; and/or iii) a frame about the periphery of the substrate which projects beyond the active material and is substantially free of the active material or dust formed from the active material; and wherein the battery plate is adapted to form part of one or more electrochemical cells in a battery assembly.

Disclosed is a battery cell assembly with improved cooling efficiency. The battery cell assembly includes a cooling fin having a tube through which a coolant flows; at least one frame member; at least one battery cell disposed to face the cooling fin; a first cooling port welded to an inlet formed at one end of the tube of the cooling fin; and a second cooling port welded to an outlet formed at the other end of the tube of the cooling fin. The first cooling port and the second cooling port are made of the same material as the tube.

An in-vehicle battery module includes a plurality of cylindrical battery cells, a battery cell holder, a protective case, a vent cover provided such that the battery cell holder is positioned between the protective case and the vent cover, the vent cover and the battery cell holder disposed such that a vent space in which gas discharged from an end face on a second-electrode side of the cylindrical battery cell flows is provided between the vent cover and the battery cell holder, at least one first-electrode bus bar, at least one second-electrode bus bar provided in the vent space, and a support member disposed partially in the vent space and the support member being configured to support the second-electrode bus bar from the vent cover side.
