Abstract

A new composite of hierarchical microspheres assembled by GeO₂ nanotubes/nitrogen doped carbon (GeO₂/NCS) derived from organic germanium complexes has been fabricated for the first time, which exhibited a high capacity of 789 mA h g⁻¹ at 1 A g⁻¹ even after 500 cycles and good rate capability.
