Experimental 3D probing techniques, such as X-ray tomography , or the more recently developed scanning spreading resistance microscopy (SSRC) , are critical when trying to extract fundamental insights about the microstructure-performance relationships of battery electrodes in general, and of graphite/Si composite in particular. However, those techniques are too costly to be used systematically, and often require not routinely accessible instrumentations, such as synchrotron beamlines. In addition, those techniques often need to find compromises between the appropriate resolution/phase contrast needed to resolve certain phases, such as the carbon binder domain (CBD) , and the sample size, which can hinder microstructural representativity .
