High-Quality Aluminum Foil For
Lithium-Ion Batteries

Lithium-ion batteries are found today in everything from hybrid and electric vehicles to consumer electronics devices like smartphones. The cathode materials in lithium battery technology are made from high-purity aluminum foil. These battery-grade aluminum foils are typically manufactured from various alloys of aluminum like 1050 and 1235.

When it comes to high-quality lithium-ion battery aluminum foil, there’s none better than the ones supplied by Inquivix Technologies. Our customers in the secondary battery manufacturing sector choose our battery aluminum foil products for their high electric conductivity, favorable thermal properties, low weight, and high performance. We also offer competitive prices, customizable products to suit your requirements and flexible shipping options.

Why Aluminum Foil Is Used For
Battery Electrode Material

In lithium-ion batteries, the current collector of the negative electrode (cathode) is made from aluminum foil, while the current collector of the positive electrode (anode) is made from copper foil. Manufacturers of lithium batteries choose cathode foil for their current collectors for the following reasons.

Electro-Chemical Stability Of Aluminum Foil

Lithium batteries undergo electrochemical reactions as part of their normal operation to convert chemical energy into electrical energy. Aluminum is chosen for the cathode foil since it has very high stability while it is in contact with other cell components. This is due to the protective layer of aluminum oxide that is formed on the surface, which prevents any unnecessary reactions with the electrolyte. This ensures safe battery performance for the end user.

Electrical Conductivity And Thermal Stability

Current collectors are chosen for their high conductivity of electricity. Aluminum foil naturally has good conductivity, and is also thermally stable over a wide range of temperatures. This is how cathodes made from aluminum foil play an important role in a wide variety of applications from high-power batteries used in electric cars to the ones used in laptops.

Lighter Weight

Aluminum is generally considered a lightweight metal that is high in mechanical strength. This is how foils made from aluminum can significantly reduce the weight of secondary battery components compared to traditional lead-acid battery technology. Rechargeable lithium-ion batteries made using aluminum foil plays an important role in the reduction of size and weight of many consumer electronics devices such as smartphones.


Aluminum depending on the alloy being used and the tempering state can be manufactured to be a soft material that is high in formability. This makes it easy to handle for secondary battery manufacturers during production.

Why Choose Inquivix Technologies For
Battery Aluminum Foil

High Purity Of The Alloy Is Guaranteed

For our manufacturing partners to produce the most advanced high-performance battery products in the world, the foils they use need to be supplied at the correct alloy purity levels. Ordinary aluminum foil that has a high level of impurities can cause the surface to corrode, and even react with the lithium.

At Inquivix Technologies, we use only the best sources of raw materials and maintain precise control over our manufacturing processes to ensure that the specific alloys used to make foils contain over 98% aluminum composition.

Cathode Foil To The Thickness You Need

With electronic components getting smaller and smaller, battery manufacturers are constantly looking for ways to develop current collectors that can be miniaturized without compromising their high performance. This can be done by reducing the thickness or gauge of the foil.

At Inquivix Technologies, we have state-of-the-art manufacturing capabilities that can develop uniformly thick aluminum foil at gauges as thin as 0.014 mm or 14 microns. Smaller and more lightweight secondary battery components can be made without any trade-offs in the mechanical strength or purity of the alloy.

Alloys Used For Battery Aluminum Foil

3003 Aluminum Coil

Aluminum 1050

Aluminum 1050 is one of the purest alloys supplied by us with over 99.5% aluminum composition. Its high conductivity, smooth surface, and formability make 1050 perfect for making foils used in secondary batteries. Furthermore, 1050 alloy can also be used for manufacturing transformer components.

8081 Aluminum Coil

Aluminum 1235

Our aluminum 1235 has an aluminum composition of 99.35% and has high plasticity, corrosion resistance, and excellent conductivity. Our customers mainly use 1235 foil for making secondary batteries, although this alloy is also capable of being useful in several applications such as making capacitors, thermal insulation, and even for packaging.


What Is Battery Aluminum Foil?

Lithium-ion battery technology requires current collectors for its cathode and anode to perform the necessary electrochemical reactions that allow a battery to charge, discharge, and recharge. The aluminum cathode foil that serves this function is called battery aluminum foil. The anode foil is made from copper foil.

What Type Of Aluminum Is Used In Lithium-Ion Batteries?

Aluminum foil has to be high in purity so that it doesn’t react in any unwanted way with the rest of the battery’s internal components. Aluminum alloy types like 1050 and 1235 which have an aluminum composition above 98% and a thickness of 0.014 to 0.2 mm are used to manufacture the cathode foils in secondary batteries.
