Geometry-dependent elastic stability map of solid and hollow alloy particles for lithium-ion battery anodes.

Alloy-type anodes such as silicon (Si), germanium (Ge), and tin (Sn) offer substantially higher theoretical capacities than conventional graphite anodes, but their practical implementation is hindered by severe volumetric expansion and diffusion-induced mechanical degradation during lithiation. Although nanoscale parti...
