Abstract Scope The performance of Ni-rich layered cathode materials is enhanced by a core-shell structure with concentration gradient. The primary particles with 10s of nm sizes are reported to agglomerate to spherical-shaped secondary particles with a few micron sizes. Complicated interconnection and void structure are present in the secondary particles, which governs the electrochemical performance of the cathodes. Furthermore, micro-cracks were observed to generate and propagate at different cycling stages. Establishing the connection between morphology and functionality desires a combination of a high-resolution tomography measurement with sub-20 nm resolution and a 3D fluorescence mapping differentiating the concentration-gradient. This scientific problem matches very well with the multi-modal 3D imaging capability provided with the scanning probe microscope using multilayer Laue lenses at the HXN beamline of NSLS-II. We simultaneously collected the far-field diffraction and the fluorescence signal, which gives a comprehensive picture of the cathode material and provides insights to understand the performance improvements.
