Postmortem analysis played a crucial role in unraveling the effects of sulfur-graphenic cathodes on their performance, and shedding light on various aspects of their behavior. Further analysis of the cell showcased in Figure (>1500 cycles), enabled a detailed examination of the sulfur-graphenic cathodes post-cycling, which allowed to assess any structural changes or degradation which may have occurred during the cell operation procedure, the results of which can be seen in Figure . weight percent of 2.6% and 6.7% respectively, as shown in the Table .
