Definitions
- the present invention relates to a battery module.
- lithium secondary batteries are receiving attention due to their advantages such as the fact that they have almost no memory effect compared to nickel-based secondary batteries, are free to charge and discharge, have a very low self-discharge rate, and have high energy density.
- the lithium secondary battery mainly use lithium oxide and carbon material as positive and negative active materials, respectively.
- the lithium secondary battery comprises an electrode assembly in which positive and negative plates, each coated with the positive and negative active materials, are arranged with a separator between them, and an outer material, i.e., a battery case, that seals and stores 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 driving or energy storage in not only small devices such as portable electronic devices but also medium and large devices such as electric vehicles and energy storage systems (ESS).
- ESS electric vehicles and energy storage systems
- a plurality of these secondary batteries can be electrically connected and stored together inside a module case to form a single battery module.

- a sudden voltage drop in the battery module or battery pack may occur. This may cause 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 the battery pack occurs suddenly while an electric vehicle is in operation, there is no time to move the electric vehicle to a safe location.
- an object of the present invention 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.
