abstract = {The theoretically possible energy and power densities of
rechargeable batteries are practically limited by
resistances as these lead to overvoltages, particularly
pronounced at kinetically harsher conditions, i.e., high
currents and/or low temperature. Charge transfer resistance
(Rct), being a major type of resistance alongside with Ohmic
(RΩ) and mass transport (Rmt), is related with the
activation hindrance of electrochemical reactions. Its
practical relevance is discussed within this work via
analyzing cells with the galvanostatic/constant current (CC)
technique. Rct at Li|electrolyte interfaces is shown to be
relevantly impacted by electrode–electrolyte interphases;
implying the electrolyte type, as well. While solid polymer
electrolytes (SPEs), e.g., based on poly(ethylene) oxide
(PEO), show negligible Rct, it is evident for commercial
liquid electrolytes and readily increase during storage.
Given the asymptotic overvoltage vs. current behavior of
Rct, obeying Butler-Volmer equation, Rct gets less relevant
at enhanced currents, as experimentally validated, finally
pointing to the dominance of RΩ and (depending on system)
Rmt in the overall resistance.},
