ABSTRACT
Electron spin resonance (ESR) is a sensitive spectroscopic method
for the investigation of local crystal structure and electronic
properties of paramagnetic species in materials. Such species
carrying the magnetic moments are often employed as active elec-
trode materials for lithium-ion batteries and their electrochemical
properties substantially determined by their structural features.
In this chapter, application of ESR method to study the electronic
structure of layered and NASICON structured cathode materials is
presented.
