Ossila S2011A1-25 is a battery grade copper foil supplied as a pack of 25 pre-cut sheets measuring 148 x 210 mm. Each sheet is 9 µm thick with a single sided polish, and the copper purity is Cu >99.9%. The foil serves as a substrate and current collector for lithium ion battery anodes and other energy storage devices.
The 9 µm single sided polish grade offers a tensile strength of ≥296 MPa, a surface dyne of 64 dyne/cm and a normal elongation of 2.6%. Choosing among foil thicknesses and polish finishes lets researchers adjust cell designs to balance conductivity against energy density.
Because the foil comes as ready-to-use sheets rather than large rolls, it removes the need to store bulky stock and suits smaller benchtop bar-coating machines. The sheets can be coated with anode active materials such as carbon black or graphite powders to build efficient, stable electrodes.
- Current collector substrate for lithium ion battery anodes.
- Substrate for electrodes in other energy storage applications.
- Coating with carbon black or graphite powders on benchtop bar-coating machines.
- Comparative testing of foil specifications in battery cell design.
