Influence of conversion material morphology on electrochemistry studied with operando X-ray tomography and diffraction


Villevieille, Claire; Ebner, Martin; Gómez-Cámer, Juan Luis; Marone, Federica; Novák, Petr; Wood, Vanessa (2015). Influence of conversion material morphology on electrochemistry studied with operando X-ray tomography and diffraction. Advanced Materials, 27(10):1676-1681.

Abstract

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