Ossila S2012A1-25 is a battery grade copper foil with a double sided polish finish and a thickness of 6 µm, supplied as pre-cut 148 x 210 mm sheets in a pack of 25. It serves as a high-purity substrate for current collectors in lithium ion battery anodes and other energy storage devices.
With copper content above 99.9% and tightly limited levels of iron, bismuth and lead, the foil offers a clean base for electrode coating. The thin 6 µm gauge helps cell designers balance conductivity against energy density, and the foil has a tensile strength of ≥270 MPa, a surface dyne of 61 dyne/cm and a normal elongation of 2.2%.
Because the foil comes as ready-to-use sheets rather than rolls, it removes the need to store bulky material and fits smaller benchtop bar-coating machines. The sheets can be coated with anode active materials such as carbon black and graphite powders to build efficient, stable electrodes.
- Current collectors for lithium ion battery anodes.
- Substrates for other energy storage electrode development.
- Coating with anode active materials such as carbon black or graphite powders on benchtop bar-coaters.
- Comparing foil specifications during cell design to balance conductivity and energy density.
