摘要

•Imaging of oxygen in lithium-rich cathodes for future batteries materials via ABF STEM.•Quantification protocols for data processing to obtain oxygen distortions with picometre accuracy and precision.•Robustness of the methodology in simulations and experiments.•Results show positional accuracies below 20 pm, for no mistilt and specific range of thicknesses.
