Figure 5
The integrated intensity Γ of the operando SANS signal [defined by equation (1)], normalized to the initial value at x = 0 (upper panel), and the cell potential (lower panel) of an Li/graphite half-cell versus the degree of lithiation (x) for rates of C/5 (red) and C/2 (green). The dashed vertical lines indicate the onset of LiC12 and LiC6 formation from XRD during charge. |
