Summary:To provide a storage device structure capable of reducing the risk of fire when an electric storage device, particularly an electric storage device stack in which a plurality of electric storage devices are stacked, is damaged or overcharged.SOLUTION: A power storage device structure consists of a power storage device and a casing that encloses the power storage device with a gap, and has a structure in which a molded body in which a fire extinguishing agent is enclosed in an acrylic polymer is placed in the gap between the power storage device and the casing. This molded body is preferably in the form of a film, a sheet, or a plate.SELECTED DRAWING: None 【課題】 蓄電デバイス、特に複数の蓄電デバイスを積層した蓄電デバイススタックの破損時や過充電時などの異常時に発火するリスクを低減することが可能な蓄電デバイス構造体を提供する。【解決手段】 蓄電デバイス構造体は、蓄電デバイスとこの蓄電デバイスを空隙を有して外包するケーシングとからなり、蓄電デバイスとケーシングとの空隙に、アクリル系ポリマーに消火剤を封入した成形体を配置した構造を有する。この成形体は、フィルム状、シート状、または板状であることが好ましい。【選択図】 なし
