High Performance Battery Materials

Cathodes, Anodes, and Electrolytes

NANOMYTE® Cathode & Anode Tapes

NEI offers a variety of cathode and anode materials for lithium-ion batteries. Our battery materials are produced through a scalable and economical solid state synthesis process, which is adaptable to different material compositions and particle morphologies. In addition to supplying the standard material compositions listed below, we can also custom produce any lithium battery material composition of your choice.

Ready-to-Ship Electrode Sheets

NEI’s standard electrode sheets are now available in ready-to-ship packages of 2, 5, or 10 sheets (per material). Standard electrode sheets are 5 in x 10 in (127 mm x 254 mm) and cast on one side of either aluminum (cathode) or copper foil (anode) current collectors. Each tape is composed of 90% active material, 5% PVDF binder, and 5% conductive carbon. NEI can also customize tape specifications (such as loading, thickness, binder, & collector) for an additional fee. Request your quote today!

Anode Tapes for Lithium-ion Batteries

NEI offers a variety of anode electrode sheets that are suitable for a wide range of applications. Standard electrode sheets are cast on 5 inch x 10 inch (12.7 cm x 25.4 cm) sheets of copper foil current collectors, single-side coated with a 90% active material loading. NEI also offers custom tailored solutions for customers with unique specification requirements. Our tapes can be modified to accommodate different active material loadings, coating thickness, and binder type / content upon request.

NANOMYTE® Anode Electrode Sheets:

Lithium Titanate Tapes

Lithium Titanium Oxide (LTO) Tapes

Lithium titanate (Li4Ti5O12,) is an electrode material with exceptional electrochemical stability, often used as the anode in lithium-ion batteries for applications that require high rate, long cycle life, and high efficiency. LTO-based batteries are considered safer and have a wider operating temperature range.

NANOMYTE® Cathode Electrode Sheets:

LCO Cathode Tapes

Lithium Cobalt Oxide (LCO) Electrode Sheets

*NEW* Lithium Cobalt Oxide (LiCoO2) was the first and most commercially successful form of layered transition metal oxide cathodes, and it is still used in the majority of commercial Li-ion batteries today. LCO is a very attractive cathode material because of its relatively high theoretical specific capacity of 274 mAh g−1, high theoretical volumetric capacity of 1363 mAh cm−3, low self-discharge, high discharge voltage, and good cycling performance.

LMO Cathode Tapes

Lithium Manganese Oxide (LMO) Electrode Sheets

Lithium manganese oxide (LiMn2O4) is a cathode material with a spinel structure, which allows the material to be discharged at high rates. LMO-based batteries are most suited for use in high rate applications.

NCA Cathode Tapes

Lithium Nickel Cobalt Aluminum Oxide (NCA) Electrode Sheets

Lithium nickel cobalt aluminum oxide (LiNi0.8Co0.15Al0.05O2) is a cathode material that has found relatively widespread commercial use. NCA has high usable discharge capacity (∼200 mAh g−1) and long storage calendar life compared to conventional Co-based oxide cathodes. NCA-based batteries are most suited for use in moderate rate applications that require high energy density.

NMC Cathode Tapes

Lithium Nickel Manganese Cobalt Oxide (NMC) Electrode Sheets

*NEW* Layered Lithium Nickel Manganese Cobalt Oxide (LiNixMnyCozO2) is a widely used class of cathode material with LiNi1/3Mn1/3Co1/3O2 (NMC111) being the most common representative. However, current research is focusing more and more on Ni-rich NMCs – such as NMC811, 622, 532 – due to their higher specific capacity and energy. Among these materials, NMC811 can deliver a high capacity of ∼200 mAh/g with an average discharge potential of ∼3.8 V (vs. Li+/Li), making it a promising positive electrode material for high energy density, lithium-ion batteries.

LFP Cathode Tapes

Lithium Iron Phosphate (LFP) Electrode Sheets

*NEW* Lithium Iron Phosphate (LiFePO4) is the representative material for olivine structured cathode materials. Its specific capacity (~170 mAh/g) is higher than that of the related lithium cobalt oxide (~140 mAh/g), however its energy density is slightly lower due to its low operating voltage. Because of its low-cost, low-toxicity, long-term stability, and well-defined performance, LFP-based batteries are finding a number of roles in vehicle use and backup power applications.

LMNO Cathode Tapes

Lithium Manganese Nickel Oxide (LMNO/Spinel) Electrode Sheets

Lithium manganese nickel oxide / spinel (LiMn1.5Ni0.5O4) is an attractive cathode candidate for next generation lithium-ion batteries, as it offers high power capability with an operating voltage of ∼4.7 V and a capacity of ∼135 mA h g−1. Due to its high potential, LMNO-based batteries have a higher energy density compared to lithium cobalt oxide and lithium iron phosphate and are used in high rate applications.
