BATTERY MODULE AND LITHIUM SECONDARY BATTERY PACK COMPRISING THE SAME

摘要

PURPOSE: A battery module equipped with a heat-radiant unit and a lithium secondary battery pack including thereof are provided to effectively remove heat, minimize welding sealing area of external cans and improve energy density. CONSTITUTION: A battery module comprises 2 or more of pouch type unit cells(1) and a module case(10) which accepts the unit cells. A thermoconductive heat-radiating unit(20) which includes more than one of heat-radiating plates(22) is inserted into the module case. The thermoconductive heat-radiating unit additionally includes supporting plates(21) which are in contact with the module case in order to support the thermoconductive heat-radiating plate by being formed into one body with the heat-radiating plate. At least one of the unit cells is accepted in the space divided by the heat-radiating plate.
