Lychee-like TiO₂@Fe₂O₃ Core-Shell Nanostructures with Improved Lithium Storage Properties as Anode Materials for Lithium-Ion Batteries.

ABSTRACT: In this study, lychee-like TiO₂@Fe₂O₃ microspheres with a core-shell structure have been prepared by coating Fe₂O₃ on the surface of TiO₂ mesoporous microspheres using the homogeneous precipitation method. The structural and micromorphological characterization of TiO₂@Fe₂O₃ microspheres has been carried out using XRD, FE-SEM, and Raman, and the results show that hematite Fe₂O₃ particles (7.05% of the total mass) are uniformly coated on the surface of anatase TiO₂ microspheres, and the specific surface area of this material is 14.72 m² g^-1. The electrochemical performance test results show that after 200 cycles at 0.2 C current density, th
