Cathode & Anode Tapes for Lithium-ion Batteries

NEI offers a variety of cathode and anode electrode sheets that are suitable for a wide range of applications. Standard electrode sheets are cast on aluminum (cathode) or copper foil (anode) current collectors and available in ready-to-ship packages of 2, 5, or 10 sheets (per material), as well as bulk quantities upon request.

  • Coated Sheet Dimensions: 5 inches x 10 inches (127 mm x 254 mm)
  • Current Collectors: Copper (10 μm) or Aluminum (16 μm)
  • Standard* Composition: 90% active material, 5% PVDF binder, 5% conductive carbon
  • Coating: Single and Double-sided sheets available, coated edge-to-edge (unless specified otherwise)
  • Calendering: All cast electrode sheets are calendered and dried before they are packaged.
  • Quantities: Available in packages of 2, 5, 10, 25, 50, & 100 sheets per material (bulk quantities upon request)

Customization

NEI also offers custom tailored solutions for customers with unique specification requirements. Tapes can be modified for an additional fee to accommodate different active material loadings, sheet and/or coating dimensions, coating thickness, and binder type / content upon request.

*Standard for most materials (except BE-150E, BE-400E, BE-70E, and BE-80E).
