Young's elastic modulus, hardness, and fracture toughness (K Ic ) of individual grains are reported for polycrystalline LiCoO 2 , a metal oxide cathode used in lithium‐ion batteries, as measured via instrumented nanoindentation (indentations within circled locations; dashed line indicates grain boundary). The wide range of K Ic does not correlate strongly with grain orientation.
