Extended Data Fig. 8

Plating and stripping curves of a Li metal symmetrical cell with LiTFSI-PEO-Li6PS5Cl HSEs with PP13 TFSI and EMIM TFSI ionic liquids. The cell with HSE-EMIM shows quick polarization after 300 h of cycling at a current density of 0.05 mA/cm2. In comparison the cell with HSE-PP13 shows a very stable over-potential (lower than 200 mV) during 800 hours of cycling, indicating a higher ionic conductivity and better interfacial stability against Li-metal.
