Foil for Lithium battery

Descriptions for cap packaging products

CSAC is the most professional aluminum foil manufacturer in Taiwan. We are able to produce the aluminum foil with high quality and performance by molting, hot pressing, cold pressing, rolling, slitting, and heat treatment process. Owing to the developments of 3C products and electric car industries, there are huge demands of lithium batteries becomes a huge demand in the market. Therefore, CSAC has also invested in developing outer cases of lithium batteries and anodic current collectors. Moreover, purifying equipment and foil slitting machines are purchased to improve product quality. CSAC expects ourselves to be well prepared to develop the new market in the near future.

Specifications and Applications

Alloy and Temper Chemical Composition Tensile Strength(N/mm2) Thickness(μM) Surface Specification Applications
8079-O Refer to Spec. ≦110 35~40 No grease on the surface Packaging for soft shell cases of lithium batteries
Alloy and Temper Chemical Composition Tensile Strength(N/mm2) Thickness(μM) Surface Specification Applications
1N30-H18 Refer to Spec. ≧110 15~20 No grease on the surface Lithium cells for automotive or consumer goods use

8079-O Foil for external packaging

Item Description
Chemical Composition Refer to Spec.
Mechanical Property Better elongation for meeting the packaging formability requirement of the lithium battery
Grease on the surface None.(surface tension >60 Dyne). Surface degreased so that the adhesiveness will be a lot better when bonding with film.
Surface quality Good surface flatness and uniformity without Al powder pollution, scratches and folds.

1N30-H18 Foil for lithium cells – anodic current collector

Item Description
Mechanical Property Tensile strength of the foil TS≧160 N/mm2. Good rollability, heat resistance, and anti-softening on coating (as below)
Grease on the surface None.(surface tension >60 Dyne). Surface degreased so that the coating will be a lot better.
Surface quality Good surface flatness and uniformity without Al powder pollution, scratches and folds.

The hydrophilicity of oil free foil - 8079 and 1N30 will be increased after being degreased.
Thus, the coherence of the film and the coating will also be improved and performed better.
