了解锂离子电池电极的微观结构形态对于改善当前锂离子电池系统的电化学性能和开发下一代电源系统至关重要。使用3D X射线成像技术，这是不断发展，提供了一个非侵入性的平台，研究电极的微观结构和性能之间的关系，在不同的时间和长度尺度。除了表征弱（X射线）吸收石墨电极在多个长度尺度，我们实现了一种方法，通过结合从吸收对比度和泽尔尼克相衬X射线图像获得的信息，在实验室X射线显微镜上获得改进的纳米级图像对比度。2016年，作者。爱思唯尔有限公司出版
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 non-invasive 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.
