Among them, lithium secondary batteries have almost no memory effect compared to nickel-based secondary batteries, and thus are free of charge and discharge. The self-discharge rate is very low and the energy density is high.

- secondary batteries are widely used not only in small devices such as portable electronic devices but also in medium and large devices such as automobiles and power storage devices. When used in such medium and large devices, a large number of secondary batteries are electrically connected to increase capacity and output.
- the pouch-type secondary battery is widely used in such a medium-large device because of its advantages such as easy lamination and light weight.
- various methods such as direct indirect water cooling and air cooling have been applied to battery packs to secure cooling performance.

- a cooling member made of metal such as a cell cover or a cooling plate for the flow or heat conduction of a refrigerant is often interposed between each secondary battery.
- the overall volume of the battery pack can be increased and the structure can be complicated. Therefore, when manufacturing a battery pack, while the processability is poor, there is a limit to miniaturization of the battery pack, there is also a problem that increases the manufacturing cost and time.
- the cooling member and the secondary battery when using a cooling member made of an electrically conductive material such as an aluminum plate, the cooling member and the secondary battery must be insulated. Therefore, in order to provide a configuration for such insulation, the structure of the battery pack must be further complicated, and the volume and the cost may also increase.

- two different secondary batteries may be adhesively fixed to one cartridge.
- the cartridge may be formed to protrude inward from the inner side and have a protrusion interposed between two secondary batteries, and two secondary batteries may be adhesively fixed to the protrusion.
- the protrusions may be formed in the left and right directions, respectively, so that the width narrows toward the inner direction.
- the secondary battery may be adhesively fixed to the cartridge while the sealing portion is folded.
- the adhesive may be a thermally conductive adhesive.
- the apparatus may further include a thermal pad interposed between the module assembly and the pack case.
- an uneven portion may be formed on the outer surface.
- the vehicle according to the present invention for achieving the above object includes a battery pack according to the present invention.
- the cartridge is made of a thermally conductive material and can discharge heat of the secondary battery through the cartridge, a cooling member such as a cooling plate or a cooling flow path inside the battery pack, particularly between the secondary batteries. It may not include.
- the heat generated from the module assembly side is directly conducted to the pack case is discharged to the outside of the battery pack. Therefore, no separate device or space for circulating the refrigerant is required, and the battery pack can be cooled by natural air circulation outside the battery pack.
- a battery pack can be provided which is excellent in cooling performance and advantageous in compactness, excellent in assembly and processability, and in which manufacturing cost and time can be reduced.
