3M and Umicore agree to deal on Li-ion cathode material

  • 19-Oct-2011 02:47 EDT

The use of a nickel, manganese, and cobalt (NMC) cathode materials for use in lithium-ion batteries is expected to increase under a licensing agreement that allows Umicore to make and sell the materials developed by 3M. The companies say the very low concentration of cobalt in the 3M NMC cathode patent will help customers avoid cost fluctuations that are typical of cathodes with high cobalt content. They also say the good thermal stability of NMC compositions in large-format battery applications contributes to improved safety performace, thereby reducing costs.
