| Outline of Final Research Achievements |
We studied the electrode mechanism systems of Li2MnO3 and Ni- and Cr-doped Li2MnO3. In the latter half of the research, we also studied MoS2/C composite anode materials for lithium-ion battery system. It was found that the electrode characteristics of the materials significantly depend on the diffusion of Li ions in the cathode materials during charge-discharge cycling. The diffusion is related to the crystalline particle size and also types and amounts of transition metal ions to be added. For the study of MoS2/C composites, it was found that the electrode characteristics are improved by using graphene as carbon.
