High-Performance Aluminum Foil for Lithium-Ion Battery Manufacturing

Product Details

Aluminum foil is widely used as substrate (current collector) for cathode materials coating in Li-Ion battery research. The naturally formed oxide layer provides the resistance to corrosion and oxidation at high potentials. 

Aluminum has a good thermal and electronic conductivity when used as current collector.

The thickness of Aluminum foil is one of key features for the battery power density. Thin thickness benefits the power density while increases the cost. Currently, 12um is the most popular thickness for battery R&D and industries. 

Note: The aluminum foil surface can be coated by carbon, cathode materials, e.g. LiFePO4, LiCoO2, upon request.
