abstract = {The influence of different processing routes and grain size
distributions on the character of the grain boundaries in
Li7La3Zr2O12 (LLZO) and the potential influence on failure
through formation of percolating lithium metal networks in
the solid electrolyte are investigated. Therefore, high
quality hot-pressed Li7La3Zr2O12 pellets are synthesised
with two different grain size distributions. Based on the
electron backscatter diffraction measurements, the grain
boundary network including the grain boundary distribution
and its connectivity via triple junctions are analysed
concerning potential Li plating along certain susceptible
grain boundary clusters in the hot-pressed LLZO pellets.
Additionally, the study investigates the possibility to
interpret short-circuiting caused by Li metal plating or
penetration in all-solid-state batteries through percolation
mechanisms in the solid electrolyte microstructure, in
analogy to grain boundary failure processes in metallic
systems.},
