Abstract
Li-ion battery electrodes are ion-milled and prepared for three-dimensional reconstruction imaging using a focused ion beam and a method of automated serial sectioning. This tool is being developed as a means to gain additional information not typically obtained with traditional microscopy in order to improve models and further understand the structure-performance relationships. Images of the morphology acquired in such a way can be entered in a mathematical model which describes the underlying processes and physical, chemical, and electrical phenomena. Modifications to the electrode fabrication process can be made to achieve the desired morphology. This three-pronged approach provides an opportunity to develop more rigorous models and allows some predictive ability in performance of a new material or electrode film.
