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.
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
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.
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.
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.
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.
