      abstract     = {Various metal deposition models have been proposed for
                      alkali metal batteries, but the experimental acces-sibility
                      of designated driving forces and characteristics of specific
                      morphologies is still limited. A combinedmethod portfolio
                      comprising operando 1D 19 F MRI, in situ 7 Li NMR, and
                      dynamic electrochemical impedancespectroscopy (EIS)
                      experiments is presented. Experimental evidence of the
                      relation of capacity-degradingdendritic Li metal growth and
                      anionic mass-transport quantities beyond Sand’s time in
                      polymer-based Limetal batteries is demonstrated. Comparison
                      of anionic mass transport and morphological changes in
                      Limetal in Li||Li and NMC 622||Li cells revealed that
                      elevated anion drift velocities within electrolytes are
                      corre-lated with pronounced dendrite growth. Higher cell
                      voltages are associated with increased anion drift
                      veloc-ities and hence dendrite growth, as reflected by a
                      2.5-fold increase in velocities in NMC 622||Li compared to
                      Li||Li cells. This highlights the potential of the
                      introduced method portfolio for experimental evaluation of
