Abstract
An exterior material to be used for a battery comprises at least one pattern part formed in a machine direction (MD) of the exterior material, wherein the MD of the exterior material is a width direction of a battery including the exterior material, and a transverse direction (TD) of the exterior material is a longitudinal direction of the battery including the exterior material.
Claims9
A battery including an exterior material, the exterior material comprising:
- at least one pattern part formed in a machine direction (MD) of the exterior material;
- and
- a sealing part enclosing the pattern part and formed by bonding parts of two surfaces of the exterior material to form a sealed space between the two surfaces, wherein
- the MD of the exterior material is a width direction of a battery including the exterior material,
- a transverse direction (TD) of the exterior material is a longitudinal direction of the battery including the exterior material,
- an edge portion of the pattern part is adjacent to the sealing part,
- a radius of curvature of the edge portion of the pattern part is smaller than a radius of curvature of a central portion of the pattern part, and
- the central portion of the pattern part is located in the width direction of the battery from the edge portion of the pattern part.
