Abstract: A battery pack includes: a case; a plurality of batteries housed in the case; at least one of a heat-insulating material or an endothermic material disposed between the plurality of batteries; and a fire extinguisher disposed in the case. The heat-insulating material suppresses heat transfer to adjacent batteries when a battery is ignited. The heat-insulating material also blocks heat after the fire is extinguished by the action of the fire extinguisher.

Abstract: A first layered product for extinguishing fire, including: a pair of substrates; and a fire-extinguishing agent-containing layer between the pair of substrates, the layer containing a fire-extinguishing agent component generating an aerosol, and a binder resin, in which a water vapor transmission rate the substrate is 12 g/m2/day or less, a second layered product, including: a fiber layer containing an organic fiber or an inorganic fiber having a high strength-heat resistance; and a resin layer, in which at least any one of the fiber layer and the resin layer contains a fire-extinguishing agent component generating an aerosol, or a third layered product, including: a pair of substrates; and a fire-extinguishing agent-containing layer between the pair of substrates, the layer containing a fire-extinguishing agent component generating an aerosol, and a binder resin, in which a water vapor transmission rate of the substrate is 15 g/m2/day or less.
