Lili Shi,Seong-Min Bak,Zulipiya Shadike,Chengqi Wang,Chaojiang Niu,Paul Northrup,Hongkyung Lee,Arthur Y. Baranovskiy,Cassidy S. Anderson,Jian Qin,Shuo Feng,Xiaodi Ren,Dianying Liu,Xiao-Qing Yang,Fei Gao,Dongping Lu,Jie Xiao,Jun Liu,Jun Liu +18 more
TL;DR: In this paper, the authors investigate the reaction processes and their correlation to cell cycling behavior and failure mechanisms, and find that catastrophic failure of high-energy Li-sulfur (Li-S) pouch cells results from uneven sulfur/polysulfide reactions and electrolyte depletion for the first tens of cycles.

Application of In Operando UV/Vis Spectroscopy in Lithium–Sulfur Batteries
Manu U. M. Patel,Robert Dominko +1 more
TL;DR: Recalculation of normalized reflections of UV/Vis spectra obtained in operando mode enable the formation of polysulfides and their concentrations to be followed and it is possible to distinguish differences in the mechanism ofpolysulfide shuttling between two electrolytes and to correlate differences in capacity fading.
