 Lithium-ion Battery Chemistry  

  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.
