Abstract
Provided are a pouch-type secondary battery, a manufacturing method thereof, and a pouch-type secondary battery manufactured therefrom. More particularly, a pouch-type secondary battery having an electrode assembly built therein wherein the pouch has an opening and one surface or both surfaces of the opening are sealed by a gas separation membrane including a porous substrate and a composite layer including a polymer, in which silver particles or a silver salt is dispersed, laminated on one surface or both surfaces of the porous substrate, a manufacturing method thereof, and a pouch-type secondary battery manufactured therefrom are provided.
Claims4
A pouch-type secondary battery having an electrode assembly housed inside a pouch,
- wherein the pouch has one or two or more openings,
- wherein one side surface or both side surfaces of the opening is sealed by a gas separation membrane using thermal bonding,
- wherein the gas separation membrane includes a porous substrate and a composite layer formed on one surface or both surfaces of the porous substrate,
- wherein the composite layer comprises a silver salt and tetracyanoquinodimethane (TCNQ) dispersed in a polymer, and
- wherein one side surface or both side surfaces of the opening is sealed by the gas separation membrane such that the composite layer faces the opening.
