Figure 6. (A) Cycling performance of MoS2/C@CNs electrode at 2,000 mA g-1 in 1M KFSI, 6M KFSI, and 0.8M KPF6 in EC: DEC electrolytes. (B-D) XPS spectra of the fully discharged MoS2/C@CNs electrodes after five cycles or 500 cycles in 0.8M KPF6, 1M KFSI, and 6M KFSI electrolytes for C 1s (B), O 1s (C) and F 1s (D).
