Figure 3. Electrochemical performance of 3L-SnS₂/Gr and p-SnS₂/Gr in SIBs. (A) Rate performances of 3L-SnS₂/Gr and p-SnS₂/Gr at various current densities; (B) Cycling stability of 3L-SnS₂/Gr at 10 A·g^-1. Inset: initial discharge-charge curve; (C) Charge/discharge curves of 3L-SnS₂/Gr at different current densities; (D) Rate performance comparison between this work and other reported literature; (E) Comparison of different anode materials according to specific capacity and energy density with SHE cathode; (F) GITT curves of 3L-SnS₂/Gr at second cycle; (G) Charge/discharge curves of full cell at different rates with 3L-SnS₂/Gr anodes with Na₃V₂(PO₄)₃ F₂ cathodes; (H) Voltage-energy density curves and optical image of assembled pouch full cell. SIBs: Sodium-ion batterys; SHE: standard hydrogen electrode; GITT: galvanostatic intermittent titration technique.
