dc.description.abstract | A novel strategy to improve the electrochemical performance of a germanium anode is proposed via encapsulating germanium nanoparticles in carbon nanoboxes by carbon coating the precursor, germanium dioxide cubes, and then subjecting them to a reduction treatment. The complete and robust carbon boxes are shown to not only provide extra void space for the expansion of germanium nanoparticles after lithium insertion but also offer a large reactive area and reduced distance for the lithium diffusion. Furthermore, the thus‐obtained composite, composed of densely stacked carbon nanoboxes encapsulating germanium nanoparticles (germanium@carbon cubes (Ge@CC)), exhibits a high tap density and improved electronic conductivity. Compared to carbon‐coated germanium bulks, the Ge@CC material shows excellent electrochemical properties in terms of both rate capability and cycling stability, due to the unique cubic core–shell structure and the effective carbon coating, so that the Ge@CC electrode delivers ≈497 mA h g−¹ at a current rate of 30 C and shows excellent cycling stability of 1065.2 mA h g−¹ at 0.5 C for over 500 cycles. | - |
