      abstract     = {For this contribution, two generations of uncompressed
                      pouch cells are investigated in cyclic aging tests. The
                      results are analyzed for the key influence factors by
                      opposing the results of both cell setup strategies with
                      results of compressed cells reported in literature. The
                      cells are evaluated with respect to pulse resistance, anode
                      overhang, dV/dQ-analysis, capacity difference analysis,
                      homogeneity of lithium distribution (HLD) and irreversible
                      capacity losses. It is shown, that uncompressed cells
                      reveal, in contrast to compressed cells, a higher HLD, which
                      is demonstrated in the missing dV/dQ flattening over aging.
                      The trends of peak heights in dV/dQ depend mainly on the
                      graphite voltage and expansion characteristics and are
                      therefore different for both cell generations due to
                      different degrees of utilization of the anode. The trends
                      are comparable to calendric aging test results. The
                      irreversible losses for uncompressed cycled cells increase
                      with cell potential while compressed cells show higher
                      losses to lower and higher SOCs caused by low HLD.
                      Therefore, uncompressed cells have a lower risk of
                      developing lithium plating for inhomogeneous distributed
                      active lithium during accelerated aging tests performing a
                      full charge. Comparing both cell generations, the lifetimes
                      show strong deviations and the largest impact is associated
                      with n/p ratio of the anode to the cathode.},
