Understanding the microstructural morphology of Li–ion battery electrodes is crucial to improving the electrochemical performance of current Li–ion battery systems and in developing next-generation power systems. The use of 3D X-ray imaging techniques, which are continuously evolving, provides a noninvasive platform to study the relationship between electrode microstructure and performance at various time and length scales. In addition to characterizing a weakly (X-ray) absorbing graphite electrode at multiple length scales, we implement an approach for obtaining improved nano-scale image contrast on a laboratory X-ray microscope by combining information obtained from both absorption–contrast and Zernike phase-contrast X-ray images.
