Customization Options

Don’t settle for a one-size-fits-all solution! NEI understands that your battery development needs are unique. That’s why we offer extensive customization options for our cathode and anode electrodes. 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 areal capacity (mAh/cm2) per side

  • Electrode Composition

    Modify the ratio of active material, conductive carbon, and binder

  • Binder Type

    Aqueous (CMC/SBR), Non-aqueous (PVDF)

  • Current Collector

    Aluminum, Copper, Carbon paper, Graphite foil, Titanium, or Stainless steel

  • Size / Format

    Modify the dimensions or length of sheets or rolls

  • Uncoated Tab Areas

    Specify the uncoated areas along the length

  • Matching

    Anodes can be matched to cathodes at your specified N/P ratio

Current Collectors

While focus is typically placed on the performance of the ‘active’ material, the current collector plays an essential role in electrode functionality. It must remain chemically stable—resisting corrosion and unwanted surface reactions—while ensuring the electrode remains well-adhered through thousands of charge-discharge cycles.

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 sodium-ion battery solution for your unique needs.
