Carbon Coated Aluminum Foil for Battery Cathode — 11+1+1um Thickness

The 11+1+1um Carbon Coated Aluminum Foil is our company's typical product. It is designed and manufactured for battery cathode current collector use. We apply conductive slurry on the surface of pre-treated aluminum foil to get a better-performing battery aluminum foil. Besides, the properties of our self-researched slurry are strictly controlled and tested to ensure the shelf life and quality of the aluminum foil.

5. Packaging

We have three steps of packaging to ensure the product is delivered to the destination without any damage.

Step 1: Using EPE foam to protect the two end faces of the aluminum foil.

Step 2: Vacuum and package with aluminum-plastic film.

Step 3: Put it in the quick-release wooden case, which is designed for customs inspection. Label affixed on each side of the crate.

6.Q&A

a.What is the minimum order quantity?

The minimum order quantity of our carbon-coated battery aluminium foil is 5,000 kg. No matter what thickness of product it is.

b.Can you customize the packaging?

Yes, we usually use quick-release wooden boxes as outer packaging, and we also accept special-dimension requests for packaging.

c.What price do we pay for a customized sample?

It depends on your customized needs. Different coating sizes result in different quantities of waste materials; therefore, there is some discrepancy in the cost of the sample. Don't worry, all the prices are well-founded.

d.Can products with even thinner thicknesses be customized?

Yes, of course. Besides the thickness scope of 10- 15 micrometres, we have successfully developed and researched thinner versions, which are only 8- 9 micrometres. And we will continue to explore new aluminum foil products with even thinner profiles.
