Electrochemical performance of SnS₂/MoS₂/DGS electrodes: a) CV curves of the first three cycles at a rate of 0.1 mV s⁻¹. b) Comparison of the proportions of the capacitive and diffusive contributions. c) Galvanostatic discharge/charge profiles of the SnS₂/MoS₂/DGS electrode at 0.2 A g⁻¹ during the first three cycles. d) In situ XRD at different discharge (D)/charge (C) depths (color online), and e) corresponding a contour plot during the initial two cycles. f) Rate performance and g) cycling performance at 0.2 A g⁻¹. The active material loading is ≈2 mg cm⁻². h) Discharged capacities of the SnS₂/MoS₂/DGS and graphite electrodes at 0.2 A g⁻¹ and temperatures ranging from 25 to −20 °C. i) Areal capacity versus areal current density of SnS₂/MoS₂/DGS electrodes with mass loadings of 2, 4, and 6 mg cm⁻². j) Comparison of the areal capacity of SnS₂/MoS₂/DGS anodes with that of representative anodes reported at different rates, including anodes from graphite, Sn‐based composites, heterojunction composites, and Si‐based composites.
