| Research Abstract |
In this study we tried to introduce anomalous valence state ions in oxide glass. We could not confirmed to introduce higher valence transition metal ions such as Fe4+, Cr4+, Mn4+ in glass by electrochemical reaction. But in sodium iron phosphate glass we found new crystalline materials, which plays cathode active materials for sodium ion batteries. Furthermore we succeeded to fabricate tin-metal nano particles in tin phosphate glass by sodium intercalation. Therefore electrochemical insertion process is suitable for the formation of nano metal particle in oxide glass.
