Figure 4
The integrated intensity Γ of the operando SANS signal [defined by equation (1)] obtained from the Li/graphite half-cell (red points) and the Li/Li cell (blue points) during one cycle at a current density of 0.32 mA cm−2 (corresponding to C/5 for the Li/graphite half-cell). The inset shows a scanning electron microscopy image of the pristine Li foil (dark areas) and Li dendrites grown on top of it. |
