Silicon Oxide-Graphite Tapes

Anode Electrode Sheets for Lithium-ion Batteries

Silicon oxide (SiOx) is an attractive active material for high-energy lithium-ion batteries, offering a significantly higher capacity than standard graphite while exhibiting less volume expansion during lithiation compared to pure silicon.

To maximize these benefits, NEI offers composite anode sheets featuring SiOx integrated into a graphite matrix. The buffering mechanism of the oxide phase and the structural support of the graphite matrix work together to accommodate volume changes and enhance overall cycling stability. Combined with an integrated network of Multi-Walled Carbon Nanotubes (MWCNTs) and a specialized binder system to maintain robust particle-to-particle electrical connectivity, these composite sheets provide a balanced, high-capacity solution designed for improved long-term performance and structural integrity.

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.
