Evaluation of ionic conduction studied by simultaneous DTA and NMR

作为全固态燃料电池或锂二次电池的电解质，期待无机玻璃、高分子电解质等固体材料。宽谱线NMR伊萨一种检测离子和/或分子扩散的灵敏技术。另一方面，DSC/DTA是检测样品的玻璃化转变、结晶、相变和熔融的不可缺少的技术。我们在总结前人工作经验的基础上，建立了核磁共振和差热分析同步测量系统。使用这个新的系统，离子扩散运动在离子液体基聚合物电解质和玻璃形成LiCl水溶液中进行了满意的评价。

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.
