Definitions
- the present invention relates to a battery module.
- 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.
- 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.
- 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.
- 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.
- multiple such battery modules can be connected to form a single battery pack.
- a battery pack contains multiple battery modules, each of which 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 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 potentially increasing its scale.
- gas or flames may be randomly discharged to the outside. If the discharge of gas or flames is not properly controlled, there is a risk that the gas or flames may be discharged toward other battery modules, causing a thermal chain reaction in the other battery modules.
- the front side of the battery module may have module terminals, which may be configured to electrically connect to other battery modules or battery packs, such as module bus bars. Therefore, if flames are discharged toward the front side of such a battery module, the module terminals may be damaged within the battery pack, causing an electrical short.
- other battery modules may be present at the front side of the battery module, if flames are discharged toward the front side of a specific battery module, the discharged flames may easily spread to other battery modules, potentially causing a fire to spread between battery modules.
- 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.
- the present invention has been created to solve the above problems, and its purpose is to provide a battery module having an improved structure so as to appropriately control the emission of flames and the like generated inside the battery module, and a battery pack and automobile including the same.
- a battery module or battery pack capable of suppressing the emission of ignitable particles can be provided.
- a battery module may include a case providing a space therein and having a top plate; a battery cell positioned inside the case; and a flexible cover covering the top plate and having a plurality of holes.

- the battery module may further include an adhesive member that combines the flexible cover and the side plate.
- the adhesive member is provided in plurality, and the plurality of adhesive members can be spaced apart along the edge of the top plate.
- the case may include an end cover positioned below the top plate, the flexible cover extending to cover the side plate, and the battery module may further include a fastening member that couples the flexible cover to the end cover.
