Abstract
Disclosed is a battery module with an improved safety by appropriately controlling venting when a thermal event occurs inside the battery module. The battery module includes a cell assembly having at least one battery cell; a module case configured to accommodate the cell assembly in an inner space thereof and having a venting hole formed therein to discharge a venting gas generated from the cell assembly; and a venting unit provided at an outer side of the module case and having a venting channel so that the venting gas discharged from the venting hole is introduced therein and discharged to the outside, the venting unit having a protrusion configured to protrude toward an outer surface of the module case from the inside of the venting channel.
