This article concerns the study of a new class of Li2MO3 oxide which presenting remarkable characteristics as cathodes material for batteries. In this study the Electronic Paramagnetic Resonance spectroscopy played a crucial role for the identification of the redox species during the cycles of load and unload.
Li2MO3 is a big family of compounds, this study opens the door to the exploration of a large number of high capacity materials.
