Hollow microspheres composed of phase-pure ZnFe2O4 nanoparticles (hierarchically structured) have been prepared by hydrothermal reaction. The unique hollow spherical structure significantly increases the specific capacity and improves capacity retention of this material. The product of each phase transition during initial discharge (ZnFe2O4 Li0.5ZnFe2O4 Li2ZnFe 2O4 → Li2O + Li-Zn + Fe) and their structural reversibility are recognized by X-ray diffraction and electrochemical characterization. The products of the deeply discharged (Li-Zn alloy and Fe) and recharged materials (Fe2O3) were clarified based on high resolution transmission electron microscopic technique and first-principle calculations.
