Pure Copper Foil is a thin, continuous metal foil deposited on the base layer of a circuit board, It is easy to adhere to the insulation layer, to accept the protective layer of printing, corrosion after the formation of circuit patterns. As an important material to made of CCL and printed circuit board (PCB).PCB copper foil (purity of more than 99.7%, thickness 5um-105um) is one of the basic materials of the electronics industry

Manufacturing Process
The Copper Foil Produced via electrodeposition from a copper sulfate solution onto a rotating titanium or stainless steel drum.The deposited copper is peeled off, then treated (roughening, heat resistance, anti-corrosion).
Rolled Copper Foil Made by cold-rolling high-purity copper cathodes into thin sheets, followed by annealing.Surface can be further treated (e.g., oxidation resistance coating).

Advantages
- It features excellent physical properties such as fine grain structure, low profile, and high elongation. In the PCB manufacturing process, it offers the advantages of short circuit etching time and highly uniform circuit etching.
- It can effectively contribute to improving the energy density of lithium batteries, provides a stable, conductive substrate onto which the anode active material slurry is coated and rolled.aligning with a major trend in the development of future power battery systems for electric vehicles-lightweighting.
- With advantages including light weight, high flexibility, improved electrolyte wetting efficiency, and reduced internal resistance of lithium batteries, it significantly enhances the specific energy and charge-discharge rate of lithium-ion batteries.Copper is electrochemically stable within the operating voltage window of the anode, meaning it does not alloy with lithium.
- It exhibits good thermal conductivity, excellent processability, ductility, and formability, along with remarkable resistance to softening and high fatigue strength.Collects and transports electrons generated during the battery's discharge phase to the external circuit. Conversely, it distributes electrons evenly during charging

FAQ
Q1: What info. should I let you know if i would like to get a quotation for the the Electrolytic copper foil?
A1: The material size (Thickness*Width*Length and total Qty). If possible, it would be more better to advise the application of the product
Then we can recommend the most suitable products with details for confirmation.
Q2:How long is your delivery time?
A2:Generally it is 5-10 days base on we have stock on hand. or 15-20 days if no inventory, then need check with our production team for lead time according to the quantity.
Q3: Do you provide samples ?
A3:Yes, if standard sizes sample is free but buyer need to pay freight cost.
Q4:What is your terms of payment ?
A4: Normal payment term is 30%TT, 70% before shipment get ready to ship
Q5: How do you guarantee the quality of the products?
A5: Each step of production and finished products will be carried out inspection by QC department before storing to the warehouse. NG products are not allowed in the completed goods warehouse.
