The flow-type energy storage device stores electricity using a fluidic material, and includes a reaction region in which charge-discharge reaction of electricity is performed by the fluidic material, wherein the reaction region has an octagonal cross-section. The shape of the reaction region is controlled to thus improve the flowability of the fluidic material, thereby providing a flow-type energy storage device that has almost constant electrical properties even when a charging and discharging cycle is repeatedly performed. Further, the structures of an inlet and an outlet are not complicated and a separate part for controlling the flow of fluid is not used in the device, and accordingly, additional costs are not incurred during a process of manufacturing the flow-type energy storage device.

Abstract: A pouch type secondary battery includes an electrode assembly and a pouch sheath material including a first pouch portion and a second pouch portion. The pouch-type secondary battery includes dual electrode leads wherein a first electrode lead is attached to the first pouch portion and a second electrode lead is attached to the second pouch portion. In the pouch-type secondary battery, electric current is interrupted by using a volumetric swelling phenomenon caused by swelling or pressure generated upon overcharge so that the battery may be prevented from being further charged. In addition, when pressure is increased by an additional reaction, venting occurs toward the inner lead portion of each of the dual electrode leads. As a result, it is possible to increase the stability of a battery cell, module and a pack received in the pouch, and thus to improve the life of a battery.
