Double Sides Conductive Graphite Coated Copper Foil For Battery Research (260mm x 230mm x 110um), 5 sheets/pack
5 sheets/pack Conductive graphite coated copper foil is a trending substrate/current collector in battery R&D and industries. Conductive graphite coated copper foil is used as an anode material in lithium ion batteries.
Compared with bare copper foil, the conductive graphite coated copper foil has several advantages, such as:
- Improved electrical conductivity and less internal resistance
- Improve adhesion at active layer/current collector interface
- Inhibition of cell polarization and short circuit caused by dendrite growth
- Prevent substrate corrosion caused by electrolyte
The overall cell performance can benefit from these advantages, including higher charge/discharge capacity, better rate capability and cycling performance.
This conductive graphite coated copper foil can be customized upon request, such as coating material, coating thickness and copper foil thickness/width. Please contact us to provide your requirements.
