Size Dependent Fracture of Silicon Nanoparticles during Lithiation.
TL;DR: This work provides direct evidence of the mechanical robustness of small Si nanoparticles for applications in lithium ion batteries, and is diametrically opposite to those obtained previously from single-phase modeling.
Journal ArticleDOI
Size-dependent fracture of silicon nanoparticles during lithiation.
TL;DR: In this article, a strong size dependence of fracture was discovered; that is, there exists a critical particle diameter of ∼150 nm, below which the particles neither cracked nor fractured upon first lithiation, and above which they initially formed surface cracks and then fractured due to lithiation-induced swelling.
