Patent ID: 8435666

Claim:
A battery module comprising a plurality of battery cells mounted in a module case in a stacked state, wherein cooling members are mounted at interfaces between the battery cells, the module case is configured in a structure in which two opposite sides of the module case are open so that corresponding portions of the battery cell stack are exposed outward through the two open opposite sides of the module case, the cooling members are partially exposed outward through the two open opposite sides of the module case, and a coolant flows along the two open opposite sides of the module case while contacting the outwardly exposed portions of the cooling members, wherein each of the cooling members comprises: a main body part disposed at the interface between the corresponding battery cells in a contact manner with both sides of the battery cells without any separate space; a connection part successively connected to one end or opposite ends of the main body part in a state in which the connection part is exposed outward from the stacked battery cells; and a perpendicularly bent part extending from one end of the connection part in one direction or in opposite directions, and wherein each of the cooling members is formed of a metal sheet exhibiting thermal conductivity.
