Nanomechanical Quantification of Elastic, Plastic, and Fracture Properties of LiCoO2

Nanomechanical Quantification of Elastic, Plastic, and Fracture Properties of LiCoO2

Young's elastic modulus, hardness, and fracture toughness (KIc) of individual grains are reported for polycrystalline LiCoO2, a metal oxide cathode used in lithium‐ion batteries, as measured via instrumented nanoindentation (indentations within circled locations; dashed line indicates grain bou...

description Young's elastic modulus, hardness, and fracture toughness (KIc) of individual grains are reported for polycrystalline LiCoO2, 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 KIc does not correlate strongly with grain orientation.
