https://imse.wustl.edu/Lithium metal batteries are attractive for next-generation energy storage since lithium metal anode can store 10 times more capacity per mass than state-of-the-art graphite anodes. However, its application in energy storage is impeded by numerous problems, such as safety and side reactions. Addressing these problems requires fundamental understanding and material designing. In this talk, I will present our recent studies on understanding and designing high-energy-density lithium metal batteries. We utilized advanced Stimulated Raman Scattering Microscopy to understand ion transport in battery electrolytes and its interaction with electrode materials. Particularly, by inducing phase transformation at the lithium/electrolyte interface, new strategies to suppress lithium dendrite growth are developed. I will also show how tuning electrolyte composition helps enhance the performance of anode-free lithium metal batteries and cathode designs in high-energy-density lithium-sulfur batteries.
