Figure 5. Electrochemical cycling performance of the FeNiS₂ QDs@SPAN composite under different temperatures and conditions. (A) Cycling performance of FeNiS₂ QDs@SPAN and SPAN electrodes at 0.5 C and 0 °C; (B) Corresponding performance at 1 C and 60 °C; (C and D) E/S ratio effects on FeNiS₂ QDs@SPAN cycling at 1 C with ratios of 10 and 14 μL mg^-1. QDs: Quantum dots; SPAN: sulfurized polyacrylonitrile; E/S: electrolyte-to-sulfur.
