NEI can custom produce or modify any lithium anode or cathode material composition of your choice – including oxide, sulfide, and carbon-coated materials. In addition to our standard materials above, NEI manufactures specialty materials for Lithium ion batteries that are not commonly found, such as coated anode and cathode powders or specialty compositions and powder morphologies. We also offer a variety of characterization & testing services aimed to help you unlock your potential and get the best performance out of your battery materials.
NEI offers a variety of cathode and anode materials that are suitable for a wide range of applications. NEI also specializes in custom synthesis of lithium-ion cathode, anode and solid electrolyte powders to impart safety, high capacity, long cycle life, high rate and good low temperature performance.
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.
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.
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.
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.
NEI specializes in developing new compositions and particle morphologies (including nanoscale particle engineering) and has been a long trusted source for customized cathode (and anode) materials used in lithium-ion batteries.
Just as is the case with lithium-ion batteries, cathode materials are a key component of Sodium-ion batteries. The composition of the cathode material determines the cell voltage and capacity, and thereby the energy density. Sodium-ion cathode materials are typically based on intercalation / de-intercalation compounds, where sodium ions provided by the cathode are inserted into the host lattice (anode) during charge and extracted during discharge, with minimal structural change in the host material.
In contrast to lithium, sodium is one of the most abundant elements in the earth’s crust. Consequently, Na-ion batteries have attracted much attention over the past few years. The choice of cathode material with a particular chemistry depends on various factors, including cell voltage, capacity, energy and power capabilities, cycle life, and temperature of operation.
NEI offers sodium-ion anode materials, such as: Sodium Metatitanate (Na2Ti3O7, monoclinic phase), Sodium Titanium Oxide (Na4Ti5O12, hexagonal phase), and Sodium Titanium Phosphate (NaTi2(PO4)3). Learn More »
NEI offers a variety of standard and custom compositions of sodium-ion cathode materials, such as: Sodium Cobalt Oxide (Na0.7CoO2+x), Sodium Manganese Oxide (Na0.7MnO2+x and Na0.44MnO2), Sodium Iron Phosphate (NaFePO4), Sodium Manganese Phosphate (NaMnPO4), Sodium Chromium Oxide(NaCrO2), Sodium Cobalt Phosphate (NaCoPO4), and Sodium Nickel Phosphate (NaNiPO4).
