Microstructures of Reduced Graphene Oxide/Sulfur Nanocomposites and Their Impacts on Lithium Storage Performances

Figure 5

Voltage profiles of CGO/S and MGO/S at the 1st and 10th discharge cycle (a), and the corresponding cycle life plot (b). Experiments were conducted at a constant 0.05 C rate at room temperature (1 C = 1672 mAh g⁻¹). Specific capacity as a function of rGO wt% for MGO/S (c) and CGO/S (d). The left -axis is based on the specific capacity of S, while the right -axis is based on the mass of the entire composite (i.e., S, rGO, and binder).
