[Abstract]
Driven by an increasing demand for storage devices with higher energy outputs and better safety, solid-state batteries have shown their potential to replace the traditional Li-ion batteries and power the future storage market. To achieve a better performance of solid-state batteries, intensive efforts are required to understand the ionic transport mechanism and interfacial structure in these devices. In this presentation, the development of multiple physical tools for investigation of ionic transport are exhibited, including the low-temperature impedance, neutron diffraction, and in-situ high-pressure measurement. The evolution of interfacial structure will also be addressed. Discussions will be placed, from both scientific and engineering points of view, on the fundamentals and problems of the battery and its key components. Finally, the efforts to achieve solid batteries with better performance are shown, including the development of new solid electrolytes, interfacial modification, and dendrite prevention.
