Outline of Final Research Achievements

One of the causes of low power density, which is the problem of all solid lithium ion batteries, is high ion conduction resistance at the electrode-electrolyte interface. It is considered that this resistance involves the space charge layer formed at the interface. In this study, we aimed to develop a new surface analysis method to measure the electric potential and lithium content near the interface and obtain knowledge of the space charge layer.

Academic Significance and Societal Importance of the Research Achievements

本研究では、全固体リチウムイオン二次電池の複合正極材料において、充放電前後での電位やリチウム分布の変化をナノスケールで可視化することに成功しました。全固体リチウムイオン二次電池の実用化に向けて壁になっていた、電極と電解質の界面における高い抵抗の原因解明につながると期待されます。本研究の手法は、多くの全固体リチウムイオン二次電池の評価へ応用可能です。また、電池の高性能化に向けた界面設計のみならず、電池劣化要因の解析など、様々な電池解析技術への応用が期待されます。
