13+1+1µm Carbon Coated Battery Aluminum Foil

13+1+1µm Carbon-Coated Battery Aluminum Foil is commonly used as the cathode current collector for batteries, it is manufactured by coating double conductive slurry on the surface of pre-treated aluminum foil; It delivers reduced resistance, superior active material adhesion, alongside oxidation and corrosion resistance, which prolongs battery cycle life and enhances cell safety.

6.Q&A

a.What is the minimum order quantity?

The minimum order quantity is 5,000 kg.

b.Can you customize the packaging?

Yes, we usually use wooden boxes as outer packaging, but we also accept special dimension requests for packaging.

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

It depends on your customized needs. In case of different coating sizes causing different quantities of waste materials, we have to calculate the sample's cost price carefully. Don't worry, the price will also be fair.

d.Can products with even thinner thicknesses be customized?

Yes, of course. Actually, in addition to single zero foil (10 -15 micrometre), we have developed thinner versions with reduced thickness, which are only 8 - 9 micrometre. Furthermore, we will continue to develop products with even thinner profiles.
