Details :

The Lithium Ion Battery Aluminum foil is become more and more popular in the new energy in the past 9 years all over the world ,especially in China and Europe. Lithium Ion Battery aluminum foil is used for the positive electrode in lithium-ion rechargeable battery.It asks for very high requirements for the surface .the usual alloy is 1060 ,1070 and 1235 .

Zhejiang New Aluminum Tech Co Ltd is one of the leader for the battery aluminum foil in China .
The battery foil produced by Zhejiang New Aluminum Technology is one of the base materials for new energy vehicle lithium batteries, which can effectively adjust the performance of power lithium batteries. The company’s battery foil customers cover CATL, BYD, Gotion High-Tech and other large Chinese lithium battery manufacturers.We also export to Japan and Europe for the LIB companies.

The characteristics for the Battery aluminum foil :

· Excels in foil flexibility
Due to its flexibility, this foil is resistant to the expansion and contraction of battery at the time of charge/discharge.
· Good in smoothness on either side
The active material to provide the functionality of battery can be applied uniformly.
· Small in foil thickness variation
Due to its small thickness variation, the coating thickness variation of active material can be suppressed.
To raise the output power, the HEV battery has a thinner active material layer than the commercial batteries.
The smaller the foil thickness variation, the smaller can be made the thickness variation of the active material.
This advantageous property of our product has been highly appreciated by every automotive battery manufacturers, and is often a decisive factor in accepting orders.

Quality Guarantee:
We have strictly quality control system from aluminium ingot to finish aluminium roll products, and test all products before packing,just in order to make double sure that only qualified product will be delivery to clients as we know even if little problem by us in our factory maybe lead to a big trouble for clients when they get .If customer need ,we can apply the SGS and BV inspection when producing or loading.

Packing and Stuffing:

Application :

Recent advances in rolling and alloy manufacturing technologies have allowed us to develop uniformly thick, high-strength battery aluminum foil for lithium-ion cell and capacitor manufacturers. Ranging from 0.01-0.03mm in thickness, our standard and etched aluminum foils are produced in commercial quantities using high-performance aluminum alloys.
