Cathode materials are the main component of Li-ion batteries; they determine the energy density of a cell through cell voltage and / or capacity. Lithium ion batteries are typically based on intercalation / deintercallation compounds, where lithium ions provided by the cathode are inserted into the host lattice (anode) during charge and extracted during discharge, with a minimal structural change in the host material. 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 provides a variety of cathode materials that are suitable for a wide range of applications. We also provide customized cathode materials based on customer needs.

Lithium Manganese Oxide (LMO) Powders »

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 (NCA) Powders »

Lithium nickel cobalt aluminum oxide (LiNi0.8Co0.15Al0.05O2) is a cathode material that provides higher capacity than LiCoO2 when both are charged to 4.2 / 4.3V. NCA-based batteries are most suited for use in moderate rate applications that require high energy density.

Lithium Manganese Nickel Oxide (LMNO / Spinel) Powders »

Lithium manganese nickel oxide / spinel (LiMn1.5Ni0.5O4) is a cathode material that can be charged at high voltage (5V). Due to the high potential, the material has a higher energy density compared to lithium cobalt oxide and lithium iron phosphate. LMNO-based batteries can be used in high energy and high rate applications. NEI’s NANOMYTE® SP-10 is produced by a novel process that leads to exceptional cycling stability.
