Description

battery module

[0001] The present invention relates to a battery module.

[0002] This application claims priority to Korean Patent Application No. 10-2024-0047537, filed April 8, 2024, and Korean Patent Application No. 10-2025-0008861, filed January 21, 2025, the entire contents of which are disclosed in the specification and drawings of the aforementioned applications are incorporated herein by reference.

[0003] As demand for portable electronic devices such as smartphones, tablet PCs, and smartwatches increases significantly and electric vehicles become increasingly widespread, research is actively being conducted on the batteries used in these devices, especially secondary batteries that can be repeatedly charged and discharged.

[0004] Currently commercialized secondary batteries include nickel-cadmium batteries, nickel-hydrogen batteries, nickel-zinc batteries, and lithium secondary batteries. Among these, lithium secondary batteries are receiving attention for their advantages of being able to charge and discharge freely, having a very low self-discharge rate, and having a high energy density, as they have almost no memory effect compared to nickel-based secondary batteries.

[0005] These lithium secondary batteries primarily use lithium oxide and carbon materials as the positive and negative electrode active materials, respectively. Lithium secondary batteries comprise an electrode assembly comprising positive and negative plates coated with the positive and negative electrode active materials, respectively, with a separator interposed between them, and an outer case, i.e., a battery case, that seals and encloses the electrode assembly together with an electrolyte.

[0006] In general, lithium secondary batteries can be classified into can-type secondary batteries in which the electrode assembly is built into a metal can and pouch-type secondary batteries in which the electrode assembly is built into a pouch of an aluminum laminate sheet, depending on the shape of the outer packaging material.

[0007] Recently, secondary batteries are widely used for power and energy storage not only in small devices such as portable electronic devices but also in medium- to large-sized devices such as electric vehicles and energy storage systems (ESS). Multiple secondary batteries can be electrically connected and housed within a module case to form a single battery module. Each secondary battery within a battery module can be referred to as a battery cell. Furthermore, multiple such battery modules can be connected to form a single battery pack.

[0008] In this way, when a battery pack contains multiple battery modules, and each battery module contains multiple battery cells, it may be vulnerable to a thermal chain reaction between battery modules or between battery cells. For example, if an event such as thermal runaway occurs within a single battery module, the propagation of this thermal runaway to other battery modules or cells must be prevented. If the propagation of thermal runaway between battery modules or battery cells is not properly prevented, an event occurring in a specific battery module or battery cell may trigger a chain reaction of thermal reactions in other battery modules or cells, potentially causing an explosion or fire, or increasing its scale.

[0009] If an event such as thermal runaway occurs in a single battery module, gas or flames may be randomly released to the outside. If the release of gas or flames is not properly controlled, the gas or flames may be released toward other battery modules, potentially triggering a thermal chain reaction in those modules. For example, a battery module may have module terminals on the front side, electrically connecting components such as module bus bars to other battery modules or battery packs. Therefore, if flames are released toward the front side of a battery module, they may damage the module terminals within the battery pack, potentially causing an electrical short. Furthermore, other battery modules may be present on the front side of the battery module. Therefore, if flames are released toward the front side of a specific battery module, the released flames may easily spread to other battery modules, potentially causing a fire to spread between battery modules.

[0010] Failure to properly control thermal transfer between battery modules or battery cells can lead to a sudden voltage drop in the battery module or battery pack. This can lead to a sudden shutdown of the device equipped with the battery module or battery pack, resulting in unexpected damage. For example, if a voltage drop in a battery pack occurs suddenly while an electric vehicle is in operation, there is no time to move the vehicle to a safe location.

[0011] Moreover, if thermal propagation between battery modules or cells fails to be properly controlled, resulting in a sudden fire or explosion, there is a high possibility of causing casualties. For example, if thermal runaway occurs in an electric vehicle, if a certain amount of time is not allowed for a full-blown fire to develop, occupants may not be able to escape safely.

[0012] In one embodiment of the present invention, a battery module having an improved structure so as to appropriately control the emission of flames and the like generated inside the battery module, a battery pack including the same, and a vehicle are provided.

[0013] In addition, one embodiment of the present invention provides a battery module structure capable of smoothly discharging venting gas generated inside the battery module.

[0014] In another embodiment of the present invention, a battery module structure capable of blocking or suppressing externally generated venting gas from flowing into the interior of the battery module is provided.

In addition, when a thermal event occurs in the battery module, the venting gas can separate the separating line and be discharged to the outside of the battery module through the first venting hole and the second venting hole.

[0061] Each battery cell (201) may extend in the front-back direction or along the X-axis direction. A plurality of battery cells (201) may be stacked in the left-right direction or the Y-axis direction. At this time, the battery cell (201) may mean a secondary battery.

In addition, the battery cell (201) may include a first sealing portion (220) that extends to the front and rear of the receiving portion (210). In addition, the battery cell (201) may include a second sealing portion (240) that extends upward of the receiving portion (210). The electrode lead (230) of the battery cell (201) may protrude to the front and rear sides of the first sealing portion (220), respectively. In particular, the battery cell (201) may be a pouch-type secondary battery. The electrode leads (230) may protrude to the front and rear of each battery cell (201). However, the shape of the battery cell (201) is not limited to a pouch shape, and may have various shapes such as a cylindrical shape or a rectangular parallelepiped shape.

[0062] The battery array (200) may include a first adhesive member (202) positioned between battery cells (201). The first adhesive member (202) may fix adjacent battery cells (201). The battery cell (201) may include a second adhesive member (250). The second adhesive member (250) may fold and fix the second sealing portion (240) toward the receiving portion (210).

[0063] The elastic pad (300) may be positioned between a plurality of battery cells (201) or a battery array (200) and the top plate (130). The elastic pad (300) may have a plate shape.

[0070] According to this configuration of the present invention, when the battery module is exposed to venting gas (g) generated from the outside, the elastic pad (300) can prevent or suppress the venting gas (g) generated from the outside from flowing into the inside of the battery module.

[0071] Referring to FIGS. 1 to 3, a battery module according to an embodiment of the present invention may include a fire cover (400).

In addition, the heat transfer member (160) may be disposed between the bottom plate (110) and the plurality of battery cells (201) or the battery array (200). The heat transfer member (160) may include a material having high thermal conductivity. For example, the heat transfer member (160) may be resin. In addition, the heat transfer member may fix the plurality of battery cells (201) or the battery array (200).
