Graphite Tapes

Anode Electrode Sheets for Lithium-ion Batteries

Graphite remains the industry-standard anode material for lithium-ion batteries due to its reliable intercalation chemistry and excellent balance of energy density, power, and cost. Its layered hexagonal structure allows for the reversible insertion of lithium ions ( $LiC_{6}$ ) with minimal overpotential. While it offers a lower theoretical capacity than materials like silicon, graphite provides a reliable balance of energy density and structural stability over many cycles.

By providing a well-characterized, ready-to-use electrode format, our graphite anode sheets allow researchers to focus on evaluating new electrolytes, separators, or cathode materials against a validated and reliable anode platform.

NANOMYTE® Graphite Electrode Sheets

NEI offers two variations of graphite electrodes: NANOMYTE® BE-200E made with natural graphite and NANOMYTE® BE-250E made with synthetic graphite.

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 customization options, such as different active material loadings, electrode composition, binder type, current collector, and more.

Safety Information

Product Safety Information

Precautions for Safe Handling

Appropriate personal protective equipment should be used at all times. Handle in a dry and well-ventilated area. Avoid creasing and folding, or actions that abrade, sand, or grind the coated surface, as this can cause the coating to delaminate or flake off, creating unnecessary dust. Avoid contact with eyes and skin. Wash hands after handling to ensure no conductive carbon particles remain on the skin.

Conditions for Safe Storage

Store sheets flat and in a dry and well-ventilated place, away from heat and moisture —ideally a desiccator or a dry box.

Note: In its manufactured state, the ingredients of this product are not respirable. Therefore, this product does not pose a physical hazard or health risk to humans or the environment.

Refer to the Safety Data Sheet for complete information on the safe handling and storage of this material.

Shipping Classification

Not hazardous for transport.

Customization Options

NEI understands that your battery development needs are unique. That’s why we offer extensive customization options for our cathode and anode electrode sheets. For a nominal fee, our electrodes can be custom tailored to your specification, such as:

Active Material Loading: specify the active loading (mg/cm2) per side
Areal Capacity: specify the desired areal capacity of the electrode (mAh/cm2) per side
Electrode Composition: modify the ratio of active material, conductive carbon, and binder
Binder Type & Content: aqueous/non-aqueous
Current Collector: Aluminum, copper, carbon paper, graphite foil, titanium, or stainless steel
Sheet Size: the sheet size can be modified from our standard 5″ x 10″ sheets
Uncoated Tab Areas: specify the uncoated areas along the length of one or both sides of the sheet

Current Collector Options

As non-traditional materials and aqueous electrolytes become more prevalent, standard copper and aluminum foils are not always sufficient. Depending on your specific application and active material, substrates such as carbon paper, graphite foil, titanium, or stainless steel may be required. NEI Corporation has developed specialized processes to deposit active materials on a wide variety of alternative current collectors, allowing you to customize your electrodes for optimal performance.

With NEI’s customizable electrode tapes, you have the power to create the perfect lithium-ion battery solution for your unique needs.

*NEI’s spec tolerance is ± 5%; some customization options are subject to availability and will increase the lead time.
