As such, this includes all cases in which one device is configured by itself or a part of a large device.
- a large battery module may be configured by connecting a plurality of small battery modules, or a plurality of unit modules may be connected by connecting a small number of battery cells.
- the unit cells may have a structure in which the refrigerant passes between the unit cells and is spaced apart from each other in a size of 5 to 50% based on the thickness of the unit cell so as to effectively cool the unit cells.
- the separation space between the unit cells is less than 5% size based on the thickness of the unit cell, it is difficult to obtain the cooling effect of the desired refrigerant, if the size exceeds 50% battery module consisting of a plurality of unit cells It is not preferable because the size of is large.
- the battery cell is a plate-shaped battery cell having a thin thickness and a relatively wide width and length so as to minimize the overall size when the battery cell is charged for the configuration of the battery module.
- a secondary battery having a structure in which an electrode assembly is embedded in a battery case of a laminate sheet including a resin layer and a metal layer, and electrode terminals protrude from upper and lower ends thereof, and specifically, a pouch type of an aluminum laminate sheet.
