Outline of Final Research Achievements |
Degradation mechanisms of insertion materials with different scales have been systematically studied to develop long-cycle-life and high-energy batteries. From these findings, we have newly designed insertion materials with new functionality as electrode materials. The nanostructured electrode material found in this study shows no volumetric change on electrochemical cycles, and this finding opens the new way to develop green and sustainable energy society with high-performance and long-life batteries.
