BATTERY MODULE WITH COOLING STRUCTURE OF HIGH EFFICIENCY

摘要

PURPOSE: A battery module is provided to improve cooling efficiency and to improve the structural stability of battery cells by forming a structure capable of simultaneously cooling and immobilizing a battery cell by coupling a heat transfer member to a cartridge. CONSTITUTION: A battery module (200) includes pouch type battery cells (100) which are laminated to face adjacent battery cells and are rechargeable; metallic heat transfer members (220) each of which is mounted between the pouch type battery cells to make the part or whole of the outer circumference thereof be inserted and fixed to a cartridge and is bent to be attached to the outer side of the cartridge; and insulating cartridges (210) forming a battery cell lamination structure by immobilizing the outer circumference of the pouch type battery cells by being mounted to the space between the sealing outer circumference of the pouch type battery cells.
