> The cell with F-SSAF electrolyte and pyrolytic graphite (PG) cathode show reversible capacities of 83, 81, 79, 77, and 75 mA h g−1 at the current densities of 20, 40, 60, 80, and 100 mA g−1 (Figure 2a).
so 83 Ah/kg (at 20 A/kg), and at a cell voltage of ~ 2V thats ~166 Wh/kg.
But it's right there in the article:
