Sale 9 10 12μm 1235 Aluminum Foil For Battery Materials - China

With the rapid growth of the electric vehicle, energy storage, and consumer electronics markets, battery energy density and safety performance have become key industry priorities.

As a critical base material for lithium-ion battery cathode current collectors, 1235 aluminum foil has a density of approximately 2.71 g/cm³ and an electrical conductivity of around 60% IACS.

With its excellent conductivity, processability, and cost-effectiveness, it has become a preferred material for many leading battery manufacturers.

To meet the demand for ultra-thin materials in lithium battery manufacturing, we offer stable supplies of high-quality 1235 battery aluminum foil in 9μm, 10μm, and 12μm thicknesses.

We control quality from the source and are committed to providing global battery customers with high-performance, highly consistent current collector solutions.

Among these options:

9μm ultra-thin aluminum foil helps reduce the weight of the current collector itself.

10μm aluminum foil balances lightweight design with processing adaptability.

12μm aluminum foil is suitable for production processes requiring greater foil strength, web-handling stability, and processing reliability.

The appropriate thickness should be selected according to the battery chemistry, coating process, calendering conditions, and customer-specific technical requirements.
