Ossila S2012C2-25 is a pack of 25 high-purity copper foil sheets intended as current collectors for lithium-ion battery anodes and other energy storage devices. This variant has a double sided polish finish, a thickness of 12 µm and a sheet size of 210 x 297 mm.
The battery grade foil has a copper content above 99.9%, with low levels of iron, bismuth and lead. At 12 µm it offers a tensile strength of at least 305 MPa, a surface dyne of 68 dyne/cm and a normal elongation of 3.0%. Choosing between thicknesses and polish types lets cell designers balance conductivity against energy density.
Because the foil comes as pre-cut sheets rather than rolls, it is easy to compare specifications without storing bulky stock, and the sheets suit compact benchtop bar-coating machines. They can be used directly from the bag and coated with anode active materials such as graphite or carbon black powders to build electrodes.
- Current collectors for lithium-ion battery anodes.
- Substrates for other energy storage applications.
- Coating with graphite or carbon black powders to fabricate anode electrodes.
- Electrode preparation on small benchtop bar-coating machines.
- Testing how foil thickness and polish affect cell design trade-offs between conductivity and energy density.
