This Ossila product (S2012B2-25) is a pack of 25 high-purity copper foil sheets intended as current collectors for lithium-ion battery anodes and other energy storage devices. Each sheet measures 210 x 297 mm, is 9 µm thick and has a double sided polish finish.
The battery grade foil has a copper content of >99.9%, with tightly limited levels of iron, bismuth and lead. At this thickness it offers a tensile strength of ≥296 MPa, a surface dyne of 64 dyne/cm and a normal elongation of 2.6%. Choosing between foil thicknesses and polish finishes lets cell designers trade off conductivity against energy density.
Supplied as pre-cut sheets rather than rolls, the foil can be used as soon as it is unpacked, saves storage space and suits smaller benchtop bar-coating machines. It is a convenient base for coating anode active materials such as graphite or carbon black powders to build electrodes for testing.
- Current collector substrate for lithium-ion battery anodes.
- Substrate for coating anode active materials such as graphite and carbon black powders.
- Electrode preparation on benchtop bar-coating machines.
- Comparative testing of foil specifications in energy storage cell design.
