      abstract     = {Garnet structured Al-substituted Li7La3Zr2O12 (Al:LLZO) is
                      a promising candidate as electrolyte in all-solid-state
                      Li-ion batteries due to its chemical stability against
                      Li-metal and high voltage cathode materials. In order to
                      ensure long-term stable operation, electrolyte crack growth
                      induced and/or the volume change of the active material on
                      the cathode side needs to be avoided, requiring in
                      particular knowledge of local and global mechanical
                      properties of the electrolyte material. Micro-pillar
                      splitting test was used for the first time on this material
                      to determine the microscopic fracture toughness of single
                      grains and compare it with conventional Vickers indentation
                      fracture toughness (VIF), which represents macroscopic
                      fracture toughness. Both methods yielded comparative
                      results. In conclusion, the micro-pillar splitting test can
                      be used as an advanced locally resolved characterization
                      method that can open up new experimental directions for
                      characterizing and understanding battery materials and
                      enable a targeted approach for material improvements.},
