Fig. 5: Electrochemical performance of Li–S cells based on various sulfur cathodes.

a Galvanostatic discharge–charge curves at 1 C (i.e., 1.68 A gs−1). b Rate performance of various sulfur cathodes at different specific current. c Cycle performance at 1 C (i.e., 1.68 A gs−1). d Long-term cycling stability at 2 C (i.e., 3.36 A gs−1). e Cycle performance of {Co4W18}/rGO/S cathodes with high sulfur loading at 0.1 C (i.e., 0.168 A gs−1). f Cycle performance of the pouch cell with sulfur loading of 3.6 mg cm−2 and E/S ratio of 5 μL mg−1 at 0.2 C (i.e., 0.336 A gs−1).
