Ossila S2012C1-25 is a high-purity copper foil supplied as a pack of 25 pre-cut sheets measuring 148 x 210 mm. This battery grade foil has a double sided polish and a thickness of 12 µm, and it is intended as a current collector substrate for Li-ion anodes and other energy storage devices.
The copper content is above 99.9%, with trace impurities kept low (Fe <0.0010%, Bi <0.00020%, Pb <0.0005%). At this thickness the foil offers a tensile strength of ≥305 MPa, a surface dyne of 68 dyne/cm and a normal elongation of 3.0%. Selecting foil thickness and polish finish lets cell designers balance conductivity against energy density.
Because the foil comes as flat sheets rather than a roll, it needs no bulky storage and suits smaller benchtop bar-coating machines. Sheets can be used directly from the bag, which makes it easy to trial different foil specifications. The foil can be coated with anode active materials such as carbon black or graphite powders to build electrodes.
- Current collector for anodes in lithium-ion battery cells.
- Substrate for electrodes in other energy storage applications.
- Coating with carbon black or graphite powders to prepare anode electrodes.
- Electrode preparation on compact benchtop bar-coating machines.
- Comparative testing of foil specifications during cell design.
