Battery Module With Reinforced Safety

Abstract: Disclosed is a battery module having a structure that is improved to be able to appropriately control discharge of gas, flames, etc. generated inside a battery module and effectively block infiltration of foreign matter from the outside. The battery module according to an aspect of the present invention comprises: a cell assembly including one or more battery cells; a module case having an inner space in which the cell assembly is accommodated and having a venting hole which is formed to allow venting gas generated from the cell assembly to be discharged therethrough; a venting unit disposed outside the module case and configured to allow the venting gas discharged from the venting hole to be introduced therein and then discharged to the outside; and a filter unit at least partially disposed inside the venting unit and configured to filter out substances introduced into the venting unit.
