Ossila S2012B1-25 is a battery grade copper foil supplied as pre-cut sheets, intended as a current collector substrate for lithium ion battery anodes and other energy storage work. This version has a double sided polish finish, a thickness of 9 µm and a sheet size of 148 x 210 mm, supplied in a pack of 25.
The foil has a copper purity above 99.9%, with tightly limited iron, bismuth and lead content. At 9 µm it offers a tensile strength of at least 296 MPa, a surface dyne of 64 dyne/cm and a normal elongation of 2.6%. Choosing among foil thicknesses and polish finishes lets cell designers trade conductivity against energy density.
Because the foil comes as ready-cut sheets rather than rolls, it can be used directly from the bag, saves storage space and fits smaller benchtop bar-coating machines. It is well suited to coating with anode active materials such as carbon black and graphite powders.
- Current collector substrate for Li-ion battery anodes.
- Substrate for electrodes in other energy storage devices.
- Coating with carbon black or graphite powders to prepare anode electrodes.
- Use on small benchtop bar-coating machines for electrode fabrication.
- Comparing foil specifications during cell design to balance conductivity and energy density.
