Operando Analysis of Lithium/Sulfur Cells with SANS and deuterated solvents

Abstract: Lithium sulfur (Li/S) batteries have a fivefold higher theoretical gravimetric energy density (2680 Wh/kgsulfur) than state-of-the-art lithium ion batteries. However, the strong fading of electrochemical storage capacity with increasing cycle number is still a major obstacle to a broad technical use despite decades of research. For a holistic view on all pertinent length scales it is important to investigate the precipitation of both solid end phases, sulfur (S8) and lithium sulfide (Li2S) on the microscopic length scale. We want to correlate the SANS results with measurements of the electrochemical impedance spectroscopy (EIS), Bragg peaks and the capacity fading curve obtained. This unique combination of measurements will give valuable information about the charge and discharge processes and the capacity fading in Li/S batteries.
