Outline of Final Research Achievements

We fabricated thin films of manganese and cobalt Prussian blue analogues. WE confirmed that these films shows high capacity and voltage in sodium-ion secondary battery cells. We further determined the host structure and valence state of the transition metals by means of ex situ synchrotron-radiation X-ray diffraction and absorption spectroscopy. By these investigations, we indicated that coordination polymer is a promising cathode material for next-generation secondary battery, sodium-ion secondary battery.
