a Relative density of LPS pellet for various fabrication pressures (theoretical LPS density of 1.88 g/cm3). b Nyquist plots from sequential EIS measurements (with time interval of 1.3 h) of Li|LPS|Li symmetric cell (with LPS pellet relative density of ~89.5%). All the intermediate curves (dashed lines) are enveloped by the initial (t = 0 h, blue solid line) and final (t = 12 h, blue solid line) curves. c Temporal evolution of bulk (SE + SEI) resistance of symmetric cells with four different LPS relative densities. d Ionic conductivity (blue curve) of LPS pellets and the initial overpotential (red curve) of the cell at current density of 0.2 mA/cm2.
