Outline of Final Research Achievements |
In this study, Compton scattering experiment was applied to the LiFePO4 positive electrode material for lithium ion battery. By combining experiment with first-principle calculation, it was cleared that the redox orbitals of this material were Fe 3d orbitals and the distortion of Fe-O octahedron structure on lithiation and delithiation process induced potential shift of the batteries. We proposed that the degree of the distortion was reduced by replacing Fe atom with Co or Ni atoms. It was shown that this replacement brings us a high-potential positive electrode material. Next, the lithium reaction distribution was measured in operando condition by applying Compton scattering technique to coin type commercial lithium-ion battery. The change of lithium composition on positive and negative electrodes was simultaneously obtained from the obtained lithium reaction distribution.
