      abstract     = {Lithium‐ion battery (LIB) cells of the 18650 format are
                      built in‐house with different amounts of an electrolyte.
                      After wetting and prior to subsequent formation, the cells
                      are opened. The electrolyte is regained by centrifuging the
                      entire jelly roll and quantified by a gas
                      chromatography‐flame ionization detector (GC‐FID) and
                      inductively coupled plasma‐optical emission spectroscopy
                      (ICP‐OES). The influence of a filling protocol applying
                      cycles with over‐ and reduced pressure is examined with a
                      focus on the electrolyte composition. No significant
                      difference is found in the ratio of linear (LC) to cyclic
                      carbonates (CCs). Furthermore, extraction by centrifugation
                      is investigated in different scenarios by simulating almost
                      “dry” cells to minimize alterations during the sample
                      preparation. The quantification of these electrolytes
                      indicates a slightly reduced amount of LC in the sample.},
