      abstract     = {The mechanism of reversible lithium intercalation in
                      graphite anodes is still not fully understood. In operando
                      Raman spectroscopy provides a sensitive means to monitor
                      structural changes during the intercalation process.
                      Analysis of the D-band to G-band intensity ratio (D/G ratio)
                      is a common method to study the structure of carbon
                      materials. However, this approach is complicated for the
                      investigation of graphite anodes during battery cycling, as
                      the D-band disappears with the onset of lithium
                      intercalation. To circumvent this issue, the D/G ratio can
                      be replaced by using the G-band full-width-at-half-maximum
                      (FWHM). In this study, an investigation of the G-band FWHM
                      during battery cell cycling is demonstrated as an
                      alternative to monitor the intercalation of lithium into a
                      graphite electrode. It was observed that lithium
                      intercalation already occurs to a small extent during
                      solid–electrolyte interphase (SEI) formation and that the
                      formation of staged intercalation compounds leads to a
                      continuous deformation of the boundary graphene layer.},
