Abstract

A secondary battery module according to the present disclosure includes a battery cell stack having a plurality of battery cells stacked and accommodated in a housing frame; a busbar frame including a coupling surface coupled to the housing frame to cover the battery cell stack and a protrusion protruding from the coupling surface outward away from the battery cell stack and having a terminal provided on an upper surface; and an insulation cover including a side cover portion coupled to cover an outer side of the protrusion and an upper cover portion disposed further inward than the side cover portion to expose the terminal at a higher position than the protrusion, wherein the busbar frame has a shielding portion protruding from the coupling surface in the upward and downward directions to shield the space between the terminal and the battery cell stack. The present disclosure having the above configuration may prevent contact between dust and the terminal even if a fire occurs in the battery cell stack and the dust is generated because the space between the battery cell stack and the terminal is closed by the shielding portion and the upper cover portion. Accordingly, it is possible to prevent progression to thermal runway or to delay the ongoing thermal runway.
