| Outline of Final Research Achievements |
We have invented the vanadium solid-salt battery (VSSB) which satisfies the properties required for the today's high-performance battery of high-energy density, safety, and low cost (J. Power Sources, 196 (2011) 4003.). The VSSB has advantages of (1) high energy density because it utilize the vanadium solid salt with the oxidation state at from II to V valencies, and (2) small packages due to the lack of moving part.
This study focused on the structure, thermodynamics, and kinetics of the vanadium solid salts which is a key material for the VSSB.
The carbon paste based CV have demonstrated a useful method to obtain infomation of kinetics and thermodynamics of solid salt as can be obtained for the solutions of active materials by conventional CV with solid electrode surface.
