Graphite & Activated Carbon Electrode Sheets

Anode Electrode Sheets

NEI provides two types of carbon anode tapes. NANOMYTE® BE-200E is a cast electrode sheet of graphite powder & NANOMYTE® BE-300E is a cast electrode sheet of activated carbon powder.

Standard electrode sheets are 5 inches x 10 inches (127 mm x 254 mm) and cast either single-sided or double-sided on 10 µm thick copper foil current collectors. NEI also offers custom tailored solutions for customers with unique specification requirements. Our tapes can also be customized to accommodate different active material loadings, coating thickness, binder type (aqueous/non-aqueous), and binder content, as well as choice of current collector.
