This Ossila copper foil (S2012A2-25) is a battery grade, high-purity copper substrate intended for use as a current collector in lithium-ion anodes and other energy storage devices. This version has a double sided polish finish, a thickness of 6 µm and a sheet size of 210 x 297 mm, supplied as a pack of 25 sheets.
The copper content is above 99.9%, with tightly limited levels of iron, bismuth and lead. Choosing a thin, double polished foil lets cell designers weigh conductivity against energy density when building test electrodes.
Because the foil comes as pre-cut sheets rather than rolls, it can go straight from the bag onto compact benchtop bar-coating machines, and there is no bulky roll stock to store. Different foil specifications can also be compared more easily. The sheets can be coated with anode active materials such as carbon black and graphite powders to prepare electrodes.
- Current collector for lithium-ion battery anodes.
- Substrate for other energy storage electrode research.
- Coating with carbon black or graphite powders to fabricate anode electrodes.
- Sheet-format use on small benchtop bar-coating machines.
