Electronic structure of spinel type Li~xFe~3-ωO~4 inserted lithium electrochemistry

Abstract

The distributions of electrons coming from the anode and reacting at an Fe3-wO4 (w = 0-0.33) cathode during discharge of a Li/LiClO4-PC/Fe3-wO4 (PC = propylene carbonate) cell were studied by Moessbauer spectroscopy. Only a small part of electrons entered into the t2g non-bonded orbit of octahedral FeO6 of Fe3-wO4, but a large no. of electrons get into and anti-bonded orbit holding higher energy.
