1100 Aluminum Foil for Lithium Battery 

1100 Aluminum Foil for Lithium Battery

It was found that the composition ratio of a 1100 aluminum foil for lithium battery alloy was 0.4 ~ 0.5% Fe, 0.1 ~ 0.2% Si, 0.1 ~ 0.15% Cu, 0.01 ~ 0.02% Ti, 0.03 ~ 0.07% Sc, 0.03 ~ 0.07% Ce, less than 0.01% Mn, and less than 0.005% Mg and Zn. At the same time, Fe+Si≤ 0.65%, Fe/Si was 2.0 ~ 4.0. The 1100 aluminum foil for lithium battery produced is not only of high yield but also of significantly improved mechanical properties. For example, the tensile strength of 1100 aluminum foil for lithium battery is up to 220 ~ 260MPa, and the elongation rate is up to 3% ~ 5%. The electrical conductivity is 32 ~ 35Ms/m, and the surface wetting tension is ≥30 dyne values. Therefore, 1100 aluminum foil has practical value for lithium battery.

Advantages of 1100 Aluminum Foil for Lithium Battery

As we have seen, the aluminum foil for lithium battery in the market currently use more pure aluminum alloy grades such as 1070 aluminum foil, 1235 aluminum foil, and 1200 aluminum foil. The commonly used thickness is between 12μm and 25μm and the delivery is in H18 temper. However, the tensile strength of these aluminum alloy foil is generally only close to 200MPa, and the elongation is only around 2.5. And because of its thin and soft material, the surface of aluminum foil has a large amount of oil, the surface wetting tension can only be kept within 30 dyne value, and the yield is also low. According to the data shown above, it is not difficult to find that the mechanical characteristic parameters of 1100 aluminum foil for lithium battery are better than those of these alloy foils. Not only that, as the aluminum foil for lithium battery gradually thinning trend and these existing aluminum alloy foils for lithium battery in the aluminum content of 99% at the same time, their tensile strength and elongation can’t meet the needs of thinning. But 1100 aluminum foil for lithium battery can satisfy the requirement of thinning in at the same time, also can effectively improve the tensile strength and elongation, while maintaining a high conductivity and high surface quality, favored by the market.
