| Outline of Final Research Achievements |
Multivalent metals are regarded as negative electrode materials for next generation battery. We developed safe electrodeposition baths, "glyme coordinated electrolytes" which do not have free glymes or uncoordinated glymes. Less volatility and higher oxidative stability has been achieved. The electrochemically active species in the electrolyte was elucidated both in the magnesium and aluminum electrodeposition baths. We concluded that electrochemically active species are largely affected by the kind of glymes. Additionally, as the outcome in which the first purpose is exceeded, an ionic liquid "state" which consists of crown ether coordinated potassium and superoxide anion and hydronium solvate ionic liquid using crownether-coordinated hydronium ion were discovered.
