Small coil 15 mic LB double shiny ED electrolytic copper foil for lithium Power battery
Description
| Type | Lithium Battery Copper Foil (Single/Double Matte) |
| Thickness | 15um |
| Width Range | 100~1300mm |
| Performance | Columnar grain structure formation. |
|
Comparing with the double shiny copper foil, the double matte type is Higher in roughness, while the tensile strength and elongation is lower. |
|
| Application | Be used for the Li-ion battery cathode carrier and current collector. |
Application:
1. Lip: mobile phone
2. Parallel hybrid electric vehicle(PHEV)
Compare between CA copper foil and ED copper foil
1. Process:RA copper foil (Rolling process),ED copper foil (Electrodeposition process)
2. RA copper foil is a flaky crystalline structure, so the strength and toughness is better than electrolytic copper foil, so most of the rolling copper foil used in flexible printed circuit boards.
3. Width: rolling copper foil width ≤ 620mm, electrolytic copper foil width ≤ 1380mm
FAQ:
Q4: Can you supply the sample?
A: We can supply samples to check the quality before bulk order. But the price will be sample price not wholesale price.
Q5. Do you test all your goods before delivery?
A: Yes, we have 100% test before delivery.
Q6. what is your standard width?
A: 520mm and 620mm,we accept customization for the width. we can cut it into any size that you demand after pass discussing.
