This is battery grade, high-purity copper foil from Ossila, made to serve as the current collector in lithium-ion anodes and in other energy storage research. Product S2011B1-25 is the single sided polish version at 12 µm thickness. It comes as a pack of 25 sheets measuring 148 x 210 mm.
The foil is Cu >99.9%, with iron, bismuth and lead held to trace levels. At 12 µm it gives a tensile strength of ≥305 MPa, a surface dyne of 68 dyne/cm and a normal elongation of 3.0%. Ossila supplies a range of thicknesses and both single and double sided polish finishes, so cell designers can trade conductivity against energy density.
The pre-cut sheets can be used as soon as they come out of the bag. They suit smaller benchtop bar-coating machines and avoid the need to store bulky rolls. They also make it simple to compare foil specifications during testing.
- Current collector substrate for lithium-ion battery anodes.
- Substrate for coating anode active materials such as graphite or carbon black to prepare electrodes.
- Electrode preparation on small benchtop bar-coating machines.
- Comparative testing of foil specifications in energy storage cell design.
