Outline of Final Research Achievements |
In this study, the redox orbitals of LixMn2O4 were revealed by using Compton scattering spectroscopy. Our analysis of Compton profiles obtained from LixMn2O4 shows that the change of electronic structure upon Li insertion was dominated by the contribution of O 2p redox orbital and Mn 3d orbitals delocalized in real space. Until now, the redox orbital of LixMn2O4 has been considered Mn 3d orbitals. This study provides us new insight of electrode reaction mechanism in the battery using LixMn2O4 positive electrode. We have performed development of non-destructive quantitation method of Li composition via Compton profile. Analysis of the line-shape of Compton profile shows linearity with Li composition in both theoretical calculations and experiments in LixMn2O4 positive electrode material over a wide range of x-values.
