The ability of the crosslinked SPE10:1:1-CL to support lithium plating-stripping at various current densities was assessed using Li||Li symmetrical cells at 50 °C, with current densities ranging from 0.05 up to 0.4 mA cm -2 . The cells showed overpotentials of 20 mV and 125 mV at 0.05 and 0.4 mA cm -2 respectively. As illustrated in Figure , the SPE can sustain plating-stripping polarization steps throughout the entire polarization period up to 0.4 mA cm -2 , demonstrating stable interfacial properties, thus compatibility with the lithium metal electrodes, and good cycling performance for a solid-state polymer electrolyte.
