| Outline of Final Research Achievements |
Synthesis of novel Li2MO3-type oxides was examined using high-pressure synthesis as a candidate of high capacity cathode materials for Li secondary batteries. Although a new Li2MO3-type phase was synthesized under high pressure, the single-phase sample could not be obtained. Electrochemical measurements and powder XRD and XAFS studies for Li2Mn0.4Ru0.6O3 and Li2RuO3 revealed the influences of cut-off voltage on cyclic properties and the charge-discharge mechanism in terms of structure and electronic state.
