Outline of Final Research Achievements

Inorganic-organic hybrid crystals containing polyoxometalate inorganic cluster anion and cationic surfactant were successfully synthesized by a simple cation-exchange solution process. Precise control of surfactant molecular structures and synthetic conditions enabled the introduction of proton, lithium, sodium, and magnesium ions. Besides, these hybrid crystals were conductive at 298 to 573 K, which could possibly applicable to new solid electrolytes for fuel-cell, lithium ion, or sodium-ion batteries.
