However, during the preparation of Si/C anodes, Si-Si bonds will break with numerous dangling bonds/defects on the surface of nm-Si, as the crystal grains are continuously nanosized.

First, the introduction of In vacancies drives the Fermi level deep into the valence band while inducing valence band flattening at the M and R points. This modification significantly enhances the density-of-states effective mass and hole concentration, yielding a superior power factor.
