Document Type and Number:
WIPO Patent Application WO/2018/048133
Kind Code:
A1
Abstract:
Provided are a pouch exterior material, a pouch type secondary battery using the same, and a manufacturing method therefor, the material enabling: an electrode assembly to be easily mounted at a correct position at a receiving portion; the pouch exterior material to be prevented from bursting during an assembly step while being an integrated type so as to improve lifespan characteristics of a battery by minimizing a sealing portion coming into contact with the atmosphere; and the energy density of a cell to improve. In the secondary battery pouch exterior material according to the present invention, two corresponding receiving portions on which the electrode assembly can be mounted are symmetrically formed on both sides with a protruding portion therebetween, and when in a state in which the side surface of the electrode assembly is mounted to be erected on the protruding portion, the receiving portions are bent along two folding lines separated from the central portion of the protrusion, and thus the bent portions are made to encompass the side edge of the electrode assembly.
