Title: Resolving the grain boundary and lattice impedance of hot-pressed Li 7La 3Zr 2O 12 garnet electrolytes

Here, the cubic-stabilized garnet solid electrolyte with a nominal composition of Li 6.28Al 0.24La 3Zr 2O 12 is thoroughly characterized by impedance spectroscopy. By varying the frequency of the applied AC signal over 11 orders of magnitude for characterizations from –100 to +60 °C, the relative contributions of grain and grain boundary conduction are unambiguously resolved.
