Outline of Research at the Start

本研究の目的は,固体電気二重層デバイスの動作原理を検証し,実用的な技術としての発展可能性について明確にすることである.電気二重層デバイスの動作原理は,電子材料/電解質界面の電気二重層形成に伴う電子材料への静電的なキャリア注入であるが,液体電解質と異なり内部での電荷補償を生じやすい固体電解質においては同様の効果の有無や多寡が未だよく分かっていない.本研究では電圧印加状態におけるその場硬X線光電子分光等の手法を用いて固体電解質界面のキャリア注入機構及び電荷補償挙動を詳細に調査し明らかにする.

Outline of Final Research Achievements

The electric double layer (EDL) effect at solid electrolyte/electrode interfaces has been attracting attention for energy and nanoelectronics applications. However, characteristic of the EDL effect for solid electrolyte is not clear and its characterization remains difficult in comparison with liquid electrolytes.In this study, we used a novel method to investigate the EDL effect and found that the EDL effect, and its suppression at solid electrolyte/electronic material interfaces, can be characterized on the basis of the electric conduction characteristics of H-diamond-based EDL transistors(EDLTs). Whereas H-diamond-based EDLT with a Li-Si-Zr-O Li+ solid electrolyte showed EDL-induced hole density modulation, EDLT with a Li-La-Ti-O (LLTO) Li+ solid electrolyte showed negligible enhancement, which indicates strong suppression of the EDL effect. Such suppression is attributed to charge neutralization in the LLTO, which is due to variation in the valence state of the Ti ions present.

Academic Significance and Societal Importance of the Research Achievements

本研究で取り扱う固体電気二重層は,近年全固体電池やキャパシタなどのエネルギーデバイスの出力性能と密接に関係するため,本研究はこれらの高性能化に向けた研究開発,特に界面エンジニアリングにおいて重要な役割を果たし得る.本研究によって得られた固体電気二重層の解析手法はリチウム電解質に限らず幅広い固体材料に適用可能であるため,今後様々なエネルギーデバイスの研究開発において活用されるものと期待する.
