abstract = {The NASICON type solid electrolyte LATP is a promising
candidate for all-solid-state Li-ion batteries considering
energy density and safety aspects. To ensure the performance
and reliability of batteries, crack initiation and
propagation within the electrolyte need to be suppressed,
which requires knowledge of the fracture characteristics. In
the current work, micro-pillar splitting was applied to
determine the fracture toughness of LATP material for
different grain orientations. The results are compared with
data obtained using a conventional Vickers indentation
fracture (VIF) approach. The fracture toughness obtained via
micro-pillar splitting test is 0.89 ± 0.13 MPa∙m1/2,
which is comparable to the VIF result, and grain orientation
has no significant effect on the intrinsic fracture
toughness. Being a brittle ceramic material, the effect of
pre-existing defects on the toughness needs to be
considered.},
