Ossila S2011C2-25 is a battery grade copper foil intended as a current collector substrate for Li-ion anodes and other energy storage research. This version has a single sided polish, a thickness of 15 µm and a sheet size of 210 x 297 mm, supplied as a pack of 25 sheets.
The foil has a copper purity above 99.9%, with low iron, bismuth and lead levels. At 15 µm it is the thickest option in the single sided range, offering a tensile strength of ≥330 MPa, a surface dyne of 70 dyne/cm and a normal elongation of 3.3%. Choosing between foil thicknesses and polish finishes lets cell designers balance conductivity against energy density.
Because the foil comes as pre-cut sheets rather than rolls, it can be used straight from the bag, avoids the need to store bulky rolls and fits smaller benchtop bar-coating machines. The sheets can be coated with anode active materials such as carbon black or graphite powders to prepare electrodes.
- Current collector substrate for lithium ion battery anodes.
- Electrode fabrication by coating with anode active materials such as graphite or carbon black.
- Sample preparation on small benchtop bar-coating machines.
