Figure 4. Energy density estimations for ASSPE-, QSSPE- and LE-based Li-S cells with various electrolyte thicknesses (t, in ASSPE systems), liquid content (wt.%, in QSSPE systems) and E/S ratios (in LE systems). Calculations were performed with the following parameters: 1200 mAh gsulfur-1 for cathode capacity; 64 wt.% sulfur loading for LE and 50 wt.% sulfur loading for ASSPE Li-S cells. In all the cases, the negative to positive capacity ratio was set to 3.
