Description
Although a silicon-based electrode is a promising candidate as anode in Li-ion batteries, repeated cycling results in significant morphological changes of the silicon particles leading to formation of highly porous silicon structures. We applied small-angle neutron scattering (SANS) with selective contrast matching to provide quantitative insights into the solid-electrolyte-interphase (SEI) coverage around the silicon particles and filling of the evolving porosity within the electrode.
