Using In-Situ TEM to Investigate the Role of Lithium Iodide Addition to Lithium Thiophosphate

To keep up with consumer demand for electric and hybrid vehicles, energy storage devices with higher energy and power densities, as well as higher cycle life, are needed. To meet this need, Li metal anode batteries have recently presented themselves as ideal candidates with maximum theoretical specific capacity ten-fold that of commercially used anodes like graphite. Liquid Li-sulfur is one battery system that has come to the forefront in this research field because of its high theoretical capacity and low cost.
