Carbon Electrode Sheets

NEI provides three types of carbon anode tapes:

  • NANOMYTE® BE-200E is a cast electrode sheet of natural graphite cast on Copper and used as an anode
  • NANOMYTE® BE-300E-Cu is a cast electrode sheet of activated carbon cast on Copper and used as an anode
  • NANOMYTE® BE-300E-Al is a cast electrode sheet of activated carbon cast on Aluminum and used as a cathode
  • NANOMYTE® BE-500E is a cast electrode sheet of hard carbon cast on Copper and used as an anode for either Li-on or Na-ion batteries

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.
