ELECTRICITY STORAGE DEVICE

WIPO Patent Application WO/2018/097092

A1

The purpose of the present invention is to provide a configuration of an electricity storage device in which a plurality of electricity storage bodies and cooling members are alternately arranged, the configuration making it possible to reliably prevent a decrease in cooling performance due to expansion of the electricity storage bodies. An electricity storage device 1 is provided with a heat transfer sheet 30 which is arranged between an electricity storage body 21 and a water jacket 40 and which is capable of being elastically deformed. The water jacket 40 has formed therein a fluid distribution section 70 in communication with a cooling fluid inlet of the water jacket 40, a fluid recovery section 72 in communication with a cooling fluid outlet of the water jacket 40, and a heat exchange section 67 which connects the fluid distribution section 70 and the fluid recovery section 72 via a fluid passageway 71 partitioned by fins 80 rising in the thickness direction of the water jacket 40. The heat transfer sheet 30 is arranged in an area which corresponds to the heat exchange section 67 on the surface of a body section 41 and which does not overlap the fluid distribution section 70 and the fluid recovery section 72.
