| Abstract Scope |
High-performance, low-cost fast ion conductors are essential for advancing energy technologies such as solid-state batteries, fuel cells, and sensors. A fundamental understanding of ion transport—both within the bulk and across interfaces, including grain and phase boundaries—is critical for designing efficient materials. In this talk, I will present insights into ion transport mechanisms in ceramics, glasses, glass-ceramics, and organic-inorganic hybrid materials. These insights are primarily derived from magnetic resonance characterizations, complemented by diffraction techniques, electron microscopy, and molecular dynamics simulations. Building on this understanding, we have developed a range of fast ion conductors that exhibit high ionic conductivity and stability, often achieved with inexpensive materials. I will also discuss strategies for tuning chemical compositions and mesoscale structures at interfaces to overcome transport bottlenecks and further enhance performance. |
