Optimized cell conditions for a high-energy density, large-scale Li-S battery

Summary The electrochemical performance of Li–S cells used in large‐scale battery systems was investigated with various conditions. Li/S cells were fabricated with different loading thicknesses and electrolyte ratios and used in coin cells and single‐sided and double‐sided pouch cells. The optimal conditions for the Li/S cell were as follows: a loading thickness of 28 µm and an electrolyte ratio of 20 ul/mg_S. The coin and single‐sided and doubled‐pouch cells had discharge capacities of 1009, 973, and 939 mAh/g, respectively. Copyright © 2015 John Wiley & Sons, Ltd.
