X-ray diffraction computed tomography reveals inner structure in batteries

Combining X-ray diffraction and PDF with computed tomography allows for spatially resolved structural analysis, which can help unravel structures in heterogeneous materials and map out the phases present in the system. We recently demonstrated this in a paper on complex structures in batteries, where we were able to map out the components in commercial AAA batteries and lab-scale coin cell batteries. The figure below illustrates the spiral construction of a AAA battery, showing e.g. the anode, cathode and steel construction
