      abstract     = {The further increase of practically usable specific
                      energies in lithium ion batteries (LIBs) can be realized by
                      minimizing the specific capacity losses, e.g., via
                      electrolyte additives. However, the interpretation of
                      research results of additive effects on the performance is
                      challenging, because even for identical materials and
                      conditions different effects on performance are observed,
                      rendering the validity, evaluation, and comparison of
                      electrolyte additives difficult. In this work, we show that
                      such ambiguity can be significantly influenced by the
                      quality of the used benchmark system, i.e., the
                      cell/electrolyte system without additive. The additive
                      effects are low when the used benchmark system performs
                      well. Vice versa, in poor performing cell/electrolyte
                      systems, the effect of the same additive appears strong.
                      Hidden and inconspicuous cell parameters, e.g., the type of
                      graphite electrode preparation prior to cell assembly (e.g.,
                      calendered vs hand-pressed graphite electrodes), can
                      significantly affect the performance of the benchmark system
                      and, thus, in turn the resulting additive effect. It is
                      shown that calendered graphite electrodes reveal a better
                      performance in the LIB cell than hand-pressed graphites but
                      have a lower relative additive effect (i.e., lower capacity
                      increase), while absolute performance and practical
                      relevance of the data is better. Overall, for a valid and
                      systematic additive research the use of an
                      application-oriented and, thus, optimized benchmark system
                      is recommended.},
