Fig. 1: LSB cell structure and performance sensitivity to design parameters.
From: Performance benchmarking and analysis of lithium-sulfur batteries for next-generation cell design
a The structure of a typical LSB cell with a functional sulfur host at the cathode together with an associated list of critical design parameters. b Sensitivity of an LSB cells’ specific energy to reversible discharge capacity, sulfur loading, and E/S ratio, as calculated using Eq. 1, for sulfur content of 56 wt% and c sulfur content of 80 wt.%. Dotted line, dashed line, and solid line indicate reversible discharge capacity (\({Q}_{{rev}}^{s}\)) of 1000, 1250, and 1500 mAh/g, respectively. d Heatmap of discharge capacity at 0.1 C (representing \({Q}_{{rev}}^{s}\)) as a function of sulfur loading and the E/S ratio. e Pairwise correlations between sulfur loading, electrolyte-to-sulfur (E/S) ratio, specific energy, and normalized capacity retention (see Methods).
