Study of Cathode Materials for Li Ion Batteries with EPR and High Field EPR Spectroscopy

In this work we present EPR measurments done with electrode materials
from Li ion batteries. A comparison of different systems shows, why EPR is
useful studying cathode and anode materials as well as degradation. For the
interpretation of the EPR spectra, high filed measurements, measurments at
different temperatures and in situ measurements are very useful.
