Abstract

The present disclosure relates to a fire extinguishing composition and a battery pack including the same. The fire extinguishing composition includes an inorganic compound and a polycarboxylic acid compound in a predetermined content ratio and controls viscosity at room temperature to a predetermined range, thereby being capable of uniformly forming a fire extinguishing film at points where events occur when thermal events occur in battery packs, and thus has characteristics of high cooling effect and suffocating effect for fire extinguishing. In addition, the battery pack including the same can rapidly detect points where thermal events occur and directly spray the fire extinguishing composition concentratedly to the corresponding points, thereby not only facilitating prevention of thermal event propagation but also having an advantage of shortening the time required to resolve the event.
