| Outline of Final Research Achievements |
For increasing the energy density of lithium ion batteries, it is vital to increase the capacity of negative material. In this study, we focused on the non-expensive transition metal oxides, which have capacities of more than two times of conventional graphite. However, due to severe volume change problem upon charging-discharing, it is difficult to obtain a good rate and cycling performance. To solve this problem, we proposed a solution combusiton synthesis to produce nano-oxide/carbon composites, which is effective to increase the rate and cycling performance of the oxide negative materials.
