X-ray diffraction and tomography are performed on intermetallic particles undergoing lithiation in a porous electrode. Differences between ensemble phase evolution that at single-particle level explored. It is found all evidence core-shell lithiation; however, with internal porosity more mechanically robust exhibit less fracture.
