| Outline of Final Research Achievements |
In recently, sodium ion batteries are focused because of its natural abundance and high energy density to alter large scale lithium ion batteries. In this study we examined as follows, 1.Crystallization behavior of sodium iron phosphate, 2.to clear the anode activity of SnO-P2O5 glass and 3. Preparation of Na2MnP2O7 glass-ceramics.
We found cathode activity of sodium iron phosphate in glassy state at first. And 72SnO-28P2O5 glass exhibits reversible sodium insertion during its electrochemical reaction. Finally, we found that Na2MnP2O7 glass ceramics exhibits unique crystallization behavior that valuable for preparation of new all-solid batteries in future.
