      abstract     = {Quantitative electrolyte extraction from lithium ion
                      batteries (LIB) is of great interest for recycling
                      processes. Following the generally valid EU legal guidelines
                      for the recycling of batteries, 50 wt $\%$ of a LIB cell has
                      to be recovered, which cannot be achieved without the
                      electrolyte; hence, the electrolyte represents a target
                      component for the recycling of LIBs. Additionally, fluoride
                      or fluorinated compounds, as inevitably present in LIB
                      electrolytes, can hamper or even damage recycling processes
                      in industry and have to be removed from the solid LIB parts,
                      as well. Finally, extraction is a necessary tool for LIB
                      electrolyte aging analysis as well as for post-mortem
                      investigations in general, because a qualitative overview
                      can already be achieved after a few minutes of extraction
                      for well-aged, apparently “dry” LIB cells, where the
                      electrolyte is deeply penetrated or even gellified in the
                      solid battery materials.},
