Product Details
Li Ion Battery 6um 8um 10um Rolled Copper Foil
Product Features:
1. For Negative Current Collector of Li-ion Battery
2. Low Roughness,High Ductility,High Strength
3. High Temperature Oxidation Resistance
Application Fields
Energy storage,power
Advantage :
- Rolled Copper Foil has extraordinary strength, bendability,
ductility and lustrous surface, plus its excellent mechanical
capacity, makes it irreplaceable as a raw material. Especially when
used for transformer, Copper Flexible Connector, CCL, FCCL, PCB,
Geothermal Film, Construction, Decoration etc.
- The copper foil made by Civen can be customized for different
temper, which including soft , quarter hard,half hard , hard
temper, even special soft and special hard temper.
- Soft temper are particularly strong demanded since it has wide
range of use. For transformer, it need soft cooper foil to avoid
high resistance and good heat radiating when it work.For copper
flexible connector , it prefer soft copper because it has good
extension and bendiablity. And for CCL,FCCLand PCB useage, the
copper they needed will depending on the surface roughness. But for
decorating and some other application, they need the copper to be
hard and then it will not be out of shape when after a period of
time.
- copper foil’s special features make it irreplaceable for most of
electronic requirements acted as thermal conductive, electricity
conductive, EMI/EMC or some other functions.
