Lithium Manganese Iron Phosphate (LMFP) Tapes

Cathode Electrode Sheets for Lithium-ion Batteries

Lithium Manganese Iron Phosphate [Li(Mn0.7Fe0.3)PO4, or LMFP] is an advanced, higher-voltage evolution of traditional olivine-structured LFP chemistry. By substituting manganese into the crystal framework, LMFP introduces a second, higher voltage plateau (~4.1 V vs. Li) alongside the characteristic iron plateau (~3.5 V vs. Li). This elevates the material’s nominal operating voltage to ~3.7–3.8 V, compared to just 3.2 V for standard LFP.

While LMFP exhibits a slightly lower practical specific capacity (~150 mAh/g) than LFP (~155–165 mAh/g), its higher voltage plateau generates a 15% to 20% increase in overall energy density while retaining the robust thermal safety, long cycle life, and low cost of olivine phosphates. Because its working voltage window matches that of layered oxide chemistries like NMC and LCO, LMFP serves as a compelling, cobalt- and nickel-free drop-in alternative for high-energy cell designs.

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.
