Assembled battery

Abstract

An assembled battery includes: a plurality of batteries, each with a container that contains an electric charger/discharger and an electrolytic solution and a gas discharge unit on its one surface, wherein the plurality of batteries are stacked so that the one surface of each battery is aligned to be flush with the one surface of the other batteries; a metal first flow path member is placed opposite the surface with the gas discharge unit, and configures a first flow path unit for gas discharged from the gas discharge units of the batteries; a second flow path member that forms a second flow path unit with a smaller flow path cross-sectional area; a connector that couples the first and the second flow path unit via an opening in the first flow path member; and a guide member that partitions a space inside the connector. This configuration allows for efficient gas discharge.
