                      separation and identification of constituents from common
                      organic carbonate solvent-based electrolyte systems in
                      lithium ion batteries (LIBs) is presented in this work. The
                      method development was conducted for the qualitative
                      structural elucidation of electrolyte main constituents with
                      a special focus on the aging products of these components.
                      The determination of their limits of detection was performed
                      as well. Four different LiPF6-based LIB electrolytes were
                      investigated in this study. The selected aging procedures
                      for the electrolytes were thermal aging (storage at 60 °C
                      for 2 weeks, storage at 60 °C in the presence of 2 vol $\%$
                      water contamination for 2 weeks) and electrochemical aging
                      for 100 cycles at 2C. After thermal aging, several aging
                      products were identified. The formation of organic phosphate
                      aging products and several organofluorophosphates aging
                      products was observed after thermal aging with water.
                      Additionally, the content of carbonate aging products
                      increased. After electrochemical aging, several carbonate
                      aging products were detected. Electrochemical aging at 60
                      °C leads to the additional generation of
                      organofluorophosphate aging products.},
