Abstract:

Achieving practical solid-state batteries requires advances in solid electrolytes, high-capacity electrodes, and stable solid–solid interfaces. In this talk, I will discuss our recent efforts to address these challenges across both lithium- and sodium-based solid-state battery systems. For lithium-based solid-state batteries, I will introduce strategies for developing thin solid electrolyte architectures, regulating organic-inorganic interfaces, and stabilizing electrode/electrolyte contacts to enable high-energy-density configurations. Particular attention will be given to the suppression of Li dendrite growth and interfacial degradation through electrolyte design and interfacial engineering. Advanced characterization approaches will also be discussed to reveal the evolution of solid-solid interfaces during cycling, including interfacial reactions, contact loss, and chemo-mechanical degradation. Beyond lithium, sodium-based solid-state batteries provide a promising pathway toward sustainable and cost-effective energy storage. I will discuss our recent progress in stabilizing Na-metal interfaces to suppress dendrite formation and improve cycling stability. In addition, the development of high-capacity phosphorus anodes will be presented, focusing on strategies to overcome low coulombic efficiency and sluggish reaction kinetics.
