(A) Long-term plating/stripping test in Li|PEO/LSTZ|Li symmetric cell at 100 μA cm−2, and (B) at current densities from 50 to 600 μA cm−2 at 45 °C. (C) The surface of Li metal after cycling the symmetric cell with PEO/LSTZ electrolytes for 700 h at 100 μA cm−2 and 45 °C. (D) Impedance spectra of the symmetric cell measured after different cycling times at 45 °C.
