Characterization of electrochemical performance. Cycling performances of the cells using PST-90-Electrolyte (magenta symbols) at a current density of 2 mA cm⁻² with a deposition capacity of 1 mA h cm⁻² (a); at a current density of 2 mA cm⁻² with a deposition capacity of 2 mA h cm⁻² (b); at a current density of 2 mA cm⁻² with a deposition capacity of 3 mA h cm⁻² (c). The black and blue symbols represent data of the samples using the control electrolyte and the S-Electrolyte, respectively. d The electrochemical performance of the Li-S batteries using electrolytes containing different additives at a rate of 1C. The Ketjen Black (KB) containing 70 wt% S was used as the cathode material. The areal sulfur loading is 1.5 mg cm⁻²
