Abstract: 
The discharging and charging of batteries require ion transfer across
phase boundaries. In conventional lithium-ion batteries, Li⁺
ions have to cross the liquid electrolyte and only need to pass the
electrode interfaces. Future high-energy batteries may need to work as
hybrids, and so serially combine a liquid electrolyte and a solid
electrolyte to suppress unwanted redox shuttles. This adds new
interfaces that might significantly decrease the cycling-rate
capability. Here we show that the interface between a typical
fast-ion-conducting solid electrolyte and a conventional liquid
electrolyte is chemically unstable and forms a resistive solid-liquid
electrolyte interphase (SLEI). Insights into the kinetics of this new
type of interphase are obtained by impedance studies of a two-chamber
cell. The chemistry of the SLEI, its growth with time and the influence
of water impurities are examined by state-of-the-art surface analysis
and depth profiling.
