Figure 3
The operando determined macroscopic scattering cross section dΣ/dΩ versus q for fully delithiated graphite (black symbols) and for the fully lithiated LiC6 phase (red symbols) measured in the Li/graphite half-cell. The green symbols represent the difference between the SANS signal from fully delithiated graphite and that from the LiC6 phase. The SANS cross sections shown here were corrected for detector dead time and beam intensity. Error bars are calculated from the detector and beam errors and indicate the overall SANS data point error. The integrated intensity value Γ described in the text was determined by integration over the grey shaded area. |
