Outline of Final Research Achievements

Magnesium rechargeable batteries are expected as one of the candidates for next-generation batteries. However, magnesium ions, which are divalent ions, are difficult to diffuse in solids, and at present, there are no positive electrode materials comparable to lithium-ion battery electrodes. In this study, by using composite structure between carbon and active nano-materials enables stable magnesium ion insertion/extraction. Analysis of the reaction mechanism in the composite electrode, during magnesium ion insertion/extraction reaction, the middle range of ordering structure is maintained, which contributes the good cycle performance. We have developed a new electrode design guideline that can overcome the drawbacks of the multi-valent battery electrode.
