Title:
表面処理銅箔及び銅箔基板
Document Type and Number:
Japanese Patent JP7116848
Kind Code:
B2
Abstract:
Provided are an electrodeposited copper foil, a current collector, an electrode, and a lithium-ion secondary battery comprising the same. The electrodeposited copper foil has a deposited side and a drum side opposite the deposited side. In a first aspect, ΔRS between the deposited side and the drum side is at most about 95 MPa, and the deposited side exhibits a Vv in a range from about 0.15 µm3/µm2 to about 1.35 µm3/µm2. In a second aspect, the deposited side has a Sku of about 1.5 to about 6.5 and the deposited side exhibits a Vv in a range from about 0.15 µm3/µm2 to about 1.35 µm3/µm2. The characteristics are beneficial to improve the quality of the electrodeposited copper foil, thereby extending the charge-discharge cycle life of a lithium-ion secondary battery comprising the same.
