A versatile, general and template-free strategy for the construction of well-defined yolk–shell metal@carbon nanostructures is described.
1D hollow ZnFe2O4 nanotubes coated with an ultrathin nano-carbon layer are delicately constructed via an efficient template-free strategy and exhibited superior rate behaviors and a long lifespan as a competitive anode for Li-ion batteries.
The rational design and fabrication of electrode materials is a significant, yet highly challenging task.
