ELECTRODEPOSITED COPPER, AND ELECTRICAL COMPONENT AND BATTERY COMPRISING SAME |
摘要 |
Disclosed is an electrodeposited copper in which the center line average roughness (Ra), maximal height (Rmax), and ten-point average height (Rz) of an extracted surface satisfy the following expression: 1.5 ≤ (Rmax - Rz)/Ra ≤6.5. The electrodeposited copper according to the present invention exhibits high elongation while maintaining low roughness and high strength and especially has high gloss, and thus can be used for a current collector for a lithium ion secondary battery and a semiconductor packaging substrate for tape automated bonding (TAB), which is used for a tape carrier package (TCP). |
