Figure 5From: Synthesis and Characterization of Cobalt-Doped WS2 Nanorods for Lithium Battery ApplicationsCyclic voltammograms of a coin cell (vs. Li) for selected cycles of the raw WS2 electrode (a), the Co-doped WS2 electrode (b), and the Co-doped WS2 at different potential scan rates υ (μV s−1) (c), (d) show dependence of the peak height on the square root of the potential scan rate for the oxidation peakBack to article page
