Abstract

The charging rate-dependent degradation of lithium ion battery anodes based on Si/Ge core/shell nanowire heterostructure was observed. Si/Ge core/shell structure was preserved at the charging rate of 0.8 A g−1. On the other hand, compositional intermixing and loss of Si occurs at the charging rate of 20 A g−1.
