      abstract     = {Fulfilling the service life of a Lithium-Ion battery in
                      each intended application requires further understanding of
                      the cells' lifetime and reliability. Derived from
                      literature, controlling the external pressure constant on
                      Lithium-Ion battery cells is an inevitable factor to extend
                      the cycle lifetime. Thus, active knowledge of the cells'
                      strain and understanding the impact of an external pressure
                      on the impedance is mandatory to evaluate an optimum
                      pressure to improve the cell performance. This work presents
                      correlations between voltage, strain, and impedance as a
                      function of the applied constant external pressure on a
                      nickel-rich nickel-mangan-cobalt (NMC) lithium-ion pouch
                      cell. Utilizing a high precision universal testing machine
                      reveals a negligible change of the cells' maximum stroke
                      within the pressure range from 0 to 1000 kPa. Additionally,
                      an optimum pressure between 100 and 300 kPa is revealed by
                      analyzing a series of electrochemical impedance spectroscopy
                      data measured at different constant external pressures.
                      Within this pressure range the charge transfer resistance as
                      well as the diffusive processes exhibit its optimum.},
