Abstract
Herein, a single-ion polymer electrolyte is reported for high-voltage and low-temperature lithium-metal batteries
-2
that enables suppressing the growth of dendrites, even at high current densities of 2 mA cm . The nanostructured
electrolyte was introduced into the cell by mechanically processing the polymer powder via an easily scalable
process. Important for the potential application in commercial battery cells is the finding that it does not induce
aluminum corrosion at high voltages and leads to low interfacial resistance with lithium metal. These beneficial
characteristics, in combination with its high single-ion conductivity and its high anodic stability, allow for the stable
cycling of state-of-the-art lithium-ion cathodes, such as NMC and NMC , in combination with a lithium metal
111 622
anode at 20 °C and even 0 °C for several hundred cycles.
Keywords: Polymer electrolyte, single-ion conductor, lithium metal, NMC, battery
