(a) Galvanostatic charge/discharge voltage profiles at different C-rates for CPS51 (areal S loading in the cathodes = 2 mg cm⁻², electrolyte:S ratio = 30 μL mg⁻¹), (b) C-rate performance of the sulfur/carbon composites with different sulfur contents (areal S loading in the cathodes = 2 mg cm⁻², electrolyte:S ratio = 30 μL mg⁻¹), (c) Galvanostatic charge/discharge voltage profiles at different C-rates for CPS74 (areal S loading in the cathode = 5.3 mg cm⁻², electrolyte:S ratio = 20 μL mg⁻¹) and (d) C-rate performance of high sulfur loading cathodes fabricated with CPS65 and CPS74 composites (electrolyte:S ratio = 20 μL mg⁻¹).
