| Outline of Final Research Achievements |
To improve secondary battery, Mg hydride is applied to Li-ion battery. Because the reaction between Mg hydride and Li is a solid state reaction, micro and/or nano structure is essential. Mg metal is difficult to be deformed. Therefore, Mg2FeH6 was selected for this research. Synthesis condition of Mg2FeH6 was investigated and the yield reached to around 90%. Reaction between Mg2FeH6 and Li was carried out and formation of hydrogen was confirmed. To find other couples of reaction, MgH2 and light-weighted LiBH4 was selected and reaction was carried out using the ball milling method.
