High-Purity Copper Foil as Battery Current Collectors
Copper foil for lithium ion batteries and other energy storage applications
Specifications | Gallery | Related Materials
High-purity copper foil substrate for use as current collectors in Li-ion anodes and other energy storage applications. This battery grade foil is available in a variety of thicknesses and both single and double sided polish finishes. This gives flexibility in cell design, balancing conductivity and energy density.
Pre-packaged sheets simplify testing different specifications while eliminating the need to store bulky rolls and fit on smaller benchtop bar-coating machines - ready to use straight out of the bag.
In addition to copper foils, we offer a range of anode materials that can be purchased separately. These materials, such as carbon black and graphite powders, are ideal for coating the foils, enabling the production of highly efficient and stable electrodes tailored to your specific needs.
