Here, we present a comprehensive imaging protocol for commercial Li-ion batteries and discuss the relevant understanding that is achieved at each length scale. The study begins using 2D light microscopy for fast overview imaging, followed by non-destructive 3D imaging with X-Ray and focused ion beam microscopy (XRM and FIB-SEM, respectively) to capture the fine details of the transport pathways. Complementary spectroscopic analysis with EDS and Raman microscopy further clarifies the 2D and 3D results, by providing chemical information to identify the structures. Finally, time-evolution (4D) imaging studies with non-destructive XRM elucidate the change that occur within the battery microstructures as a function of aging. Applying the techniques outlined above creates a unified spatial and chemical representation of the structure that can be used for subsequent modeling and simulation studies. The results of some example studies will additionally be presented, in order to illustrate the true power of image-based characterization.
