1. An energy storage module comprising:
a cover member accommodating a plurality of battery cells in an internal receiving space, each of the battery cells comprising a vent;
a top plate above the battery cells in a first direction, coupled to a top of the cover member, and comprising a duct corresponding to the vent of at least one of the battery cells;
a top cover above the top plate in the first direction, coupled to a top of the top plate, and having an exhaust area corresponding to the duct, the exhaust area having a plurality of discharge openings, the top cover comprising a protrusion protruding in the first direction from a bottom surface of the top cover, the protrusion extending around a periphery of the exhaust area and around a distal end of the duct; and
an extinguisher sheet between the top cover and the top plate in the first direction and offset from: (1) the protrusion of the top cover; (2) the duct of the top plate; and (3) the vent of the at least one of the battery cells in a second direction perpendicular to the first direction, the extinguisher sheet being configured to emit a fire extinguishing agent at a reference temperature to an area between the top plate and the top cover.
