NOVELTY - The pouch comprises a frame part equipped with an accommodating chamber for receiving an electrode assembly, an electrode tab tightly sealing a first sheet and a second sheet along an inner portion of the accommodating chamber. The frame part comprises a through hole in which the electrode tab is included and the electrode assembly is passes in one side of the frame part. The electrode tab of the electrode assembly passes through the through hole of the frame part. The electrode tab of the electrode assembly is fixed to a tab frame of the frame part.    USE - The pouch is useful for a secondary battery in a medium-to large-sized battery module or a battery pack of a medium-to large-sized power storage device, an electric vehicle, an electric truck, a hybrid electric vehicle and a plug-in hybrid electric vehicle (all claimed), battery electric vehicle, a wireless mobile apparatus, where the secondary battery is a lithium secondary battery.    ADVANTAGE - The pouch has simple structure, high rigidity, and occupies small area.    DETAILED DESCRIPTION - The pouch comprises a frame part equipped with an accommodating chamber for receiving an electrode assembly, an electrode tab tightly sealing a first sheet and a second sheet along an inner portion of the accommodating chamber. The frame part comprises a through hole in which the electrode tab is included and the electrode assembly is passes in one side of the frame part. The electrode tab of the electrode assembly passes through the through hole of the frame part. The electrode tab of the electrode assembly is fixed to a tab frame of the frame part. The electrode tab includes cathode and anode tabs that are placed in same direction of an electrode assembly. The frame part further includes an electrode lead that is extended and is formed from the tab frame and a groove portion. The frame part comprises a first barrier layer that is interposed between a first polymer resin layer and a second polymer resin layer. The frame part has height of 7-50 mm. The first and second barrier layers have thickness of 1-5 mm. The frame part includes a surface processing layer placed on the first polymer resin layer and the second polymer resin layer.
