In this case, the primary focus was on verifying the presence of sulfur species within the electrolyte fractions. The raw results are shown in Figure , in blue. The pristine electrolyte contains sulfur species to begin with, and as such the data was normalized against it, and is shown in orange. Notably the sulfur content in the electrolyte did increase ever-so slightly, however due to the harsh cycling conditions and the overall miniscule increase in sulfur, these results demonstrate the promising potential of our sulfur-graphenic cathodes for Li-S applications. This result, combined with the straightforward synthesis method and the previously demonstrated favorable electrochemical performance, underscores the viability and appeal of this cathode design for advancing the field of lithium-sulfur batteries.
