Reduced Graphene Oxide/MoSe2/Nitrogen-Doped Carbon Nanocomposite as Anode for Lithium-Ion-Based Dual-Ion Batteries

“…It is shown that the CV curves are similar in shape and the redox peaks are broadened, suggesting a pseudocapacitive type behavior. To further verify the existence of pseudocapacitive type behavior, the anodic/ cathodic peak currents were logarithmically plotted against scan rates (Figure 6b) based on eq 1: 44 =…”

“…It is shown that the CV curves are similar in shape and the redox peaks are broadened, suggesting a pseudocapacitive type behavior. To further verify the existence of pseudocapacitive type behavior, the anodic/cathodic peak currents were logarithmically plotted against scan rates (Figure b) based on eq : log ⁡ i = b ⁡ log ⁡ v + log ⁡ a where i and v are peak current and scan rate, respectively, while a and b are tunable values; thus b -value is determined by the slope of the plot. If b = 0.5, it reflects a diffusion-controlled behavior of the electrode; and if b = 1.0, it implies a pseudocapacitive type behavior.…”

“…In this work, the b -values are 0.81 and 0.91 for the anodic peak and cathodic peak, respectively, which reveal the coexistence of both diffusion-controlled and pseudocapacitive type behaviors. Furthermore, the contributions to the total capacities at fixed scan rates were calculated based on eq : i = k 1 ν + k 2 ν 1 / 2 where k 1 ν corresponds to the current contributions of the pseudocapacitive effects, and k 2 ν 1/2 reflects the diffusion-controlled process. As demonstrated in Figure c, 95.3% of the total capacity was contributed by pseudocapacitive type behavior at a scan rate of 2 mV s –1 .…”
