| Outline of Final Research Achievements |
Low-cost and high-efficiency batteries have been investigated for energy storage. Prussian blue, which is redox active porous coordination polymer, is focused on cathode material of ion secondary batteries. It is not reveal to relationship inner structure of PB and electrchemical behavior. In this study, I aimed to reveal effect inner structure of PB to electrochemical behavior using defect-type PB (PB-1) and perfact-type PB(PB-2).
PB-1 and PB-2 showed smoothly redox wave with potassium ion deinsertion. But, both PB did not show redox wave in lithium ion solution. On the other hand, PB-2 showed redox wave in lithium-propylene carbonate solution. Because, PB-2 is perfect type PB, and its inner environment have hydrophobic. Cu-PBA, which is PB analog displaced Fe to Cu, was synthesized and investigated electrochemical behavior. I suggest new approach for fabrication of high-performance ion secondary battery by controlling the metal species and inner environment of PB.
