1. Field
Embodiments relate to a battery module.
2. Description of the Related Art
Recently, a high output battery module using non-aqueous electrolyte of high energy density has been considered. The high output battery module may include a high capacity battery module formed by serially connecting a plurality of battery cells to be used for driving a device that requires high power, e.g., a motor of an electrical vehicle.
Typically, the battery module may include a plurality of battery cells. The battery cell may provide energy to an external electronic device by an electro-chemical reaction. The plurality of battery cells may be fixed (by a housing) to be used as a power source. The battery cell may include a highly reactive material therein, e.g., lithium. Thus, stability may be important.
