Cathode Materials for Lithium-ion Batteries
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, suitable for a wide range of applications, that are available for purchase as both powders and cast electrode tapes. We also provide customized cathode materials based on customer needs.
NANOMYTE® Cathode Powders
Our battery materials are produced through a scalable and economical solid state synthesis process, which is adaptable to different materials compositions and particle morphologies. In addition to supplying the standard cathode compositions listed below, we can custom produce any lithium battery material composition of your choice, as well as oxide, sulfide, and carbon-coated cathode materials.
NANOMYTE® Cathode Electrode Sheets
NEI offers a variety of cathode 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 aluminum 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.
