| Research Abstract |
Solid materials such as inorganic glasses and polymer electrolytes are expected as electrolytes of the all solid-state fuel cell or lithium secondary battery. Broad line NMR isa sensitive technique to detect ionic and/or molecular diffusion. On the other hand, DSC/DTA is an indispensable technique to detect glass transition, crystallization, phase transition and melt of the sample. We have constructed simultaneous NMR and DTA measurement system on the basis of our previous experiences on these techniques. Using this new system, ionic diffusional motions in ionicliquid-based polymer electorlytes and glass forming aquous LiCl solutions were evaluated satisfactorily.
