The present disclosure relates generally to a battery module having a housing and a stack of battery cells disposed in the housing. Each battery cell has a battery cell terminal and a battery cell vent on an end of each battery cell, and the battery cell vent is configured to exhaust effluent into the housing. The battery module has a vent shield plate disposed in the housing and directly along an immediate vent path of the effluent, a first surface of the vent shield plate configured to direct the effluent to an opening between the shield plate and the housing, and a second surface of the vent shield plate opposite the first surface. The battery module also has a venting chamber coupled to the opening and at least partially defined by the second surface and a vent configured to direct the effluent out of the battery module.
