      abstract     = {A major challenge of Li metal electrodes is the growth of
                      high surface area lithium during Li deposition with a
                      variety of possible shapes and growing mechanisms. They are
                      reactive and lead to active lithium losses, electrolyte
                      depletion and safety concerns due to a potential risk of
                      short-circuits and thermal runaway. This work focuses on the
                      mechanism of tip-growing Li dendrite as a particular high
                      surface area lithium morphology. Its formation mechanism is
                      well-known and is triggered during concentration
                      polarization, i.e. during mass (Li+) transport limitations,
                      which has been thoroughly investigated in literature with
                      liquid electrolytes. This work aims to give a stimulating
                      perspective on this formation mechanism by considering solid
                      polymer electrolytes. The in-here shown absence of the
                      characteristic “voltage noise” immediately after
                      complete concentration polarization, being an indicator for
                      tip-growing dendritic growth, rules out the occurrence of
                      the particular tip-growing morphology for solid polymer
                      electrolytes under the specific electrochemical conditions.
                      The generally poorer kinetics of solid polymer electrolytes
                      compared to liquid electrolytes imply lower limiting
                      currents, i.e. lower currents to realize complete
                      concen­tration polarization. Hence, this longer-lasting
                      Li-deposition times in solid polymer electro­lytes are
                      assumed to prevent tip-growing mechanism via timely enabling
                      solid electrolyte interphase formation on fresh Li deposits,
                      while, as stated in previous literature, in liquid
                      electrolytes, Li dendrite tip-growth process is faster than
                      solid electrolyte interphase forma­tion kinetics. It can be
                      reasonably concluded that tip-growing Li dendrites are in
                      general practically unlikely for both, (i) the lower
                      conducting electrolytes like solid polymer electro­lytes
                      due to enabling solid electrolyte interphase formation and
                      (ii) good-conducting electro­lytes like liquids due to an
                      impractically high current required for concentration
                      polarization.},
