4D analysis of the microstructural evolution of Si-based electrodes during lithiation : Time-lapse X-ray imaging and digital volume correlation
Silicon is a promising candidate to substitute or complement graphite as anode material in Li-ion batteries due, mainly, to its high energy density. However, the lithiation/delithiation processes of silicon particles are inherently related to drastic volume changes which, within a battery's physically constrained case, can induce significant deformation of the fundamental components of the battery
