| Outline of Final Research Achievements |
We investigated the construction of ion conduction paths in molecular crystals composed of magnesium salt and organic compounds using self-assembly and crystallization process to obtain novel solid electrolyte materials for all-solid batteries based on ubiquitous elements. Molecular crystals containing magnesium ions were synthesized by the reaction of Mg{N(SO2CF3)2}2 and ether solvents such as glyme, THF, 2-Me THF, or cyclopentyl methyl ether. Crystal structure of the obtained compounds were revealed using single crystal X-ray diffraction study as a model of the solvated structure of magnesium ions in electrolyte solution and the solid state ionic conductivity of these molecular crystals were also estimated by ac impedance method. We also developed molecular crystalline electrolytes using sodium or lithium salts and protic acid as a starting material.
