12µm High Purity Aluminum Foil

12µm High Purity Aluminum Foil serves as the mainstream cathode current collector for lithium-ion and sodium-ion batteries, supporting cathode material coating, electron collection and conduction, and is widely applied in power batteries, energy storage systems and consumer electronics cells to comprehensively balance energy density, mechanical strength and cycle life.

Key Bnenefit of 12µm High Purity Aluminum Foil

1. Lower Resistance. No-leak coating process ensures low resistance and efficient electron transfer.
2. Higher purity. Precision cleaning removes oil and impurities for stronger material adhesion.
3. Thinning and lightening. The thickness of positive electrode aluminum foil is only 12 μm. It can reduces the battery’s weight and achieving high energy density, particularly in long-range EV and 3C batteries (mobile phones, laptops).
