Template-free construction of hollow ZnFe2O4 nanotubes coated with a nano-carbon layer as a competitive anode for Li-ion batteries

Abstract

One-dimensional hollow ZnFe₂O₄ nanotubes coated with an ultrathin nano-carbon layer are delicately designed and fabricated via a facile template-free strategy and exhibit superior rate behaviors and long-term cycle stability as an anode for Li-ion batteries.
