Outline of Final Research Achievements

In the present work, framework materials having micropores were synthesized and investigated as conducting materials of polyvalent cations at room temperature for polyvalent-cation batteries. Specifically, it was clarified that divalent magnesium ions can be inserted/extracted using Prussian blue and its analogs. The possibility of the insertion and extraction of counter anions was presented in addition to the co-insertion of solvated molecules. The solvated molecules alleviated the electrostatic interaction and promoted the diffusion of magnesium ions. The above results are important for the battery applications of framework materials.
