摘要：

Three-dimensionally (3D) ordered mesoporous titania (anatase) microparticles without substrate were prepared by using polystyrene (PS) colloidal crystal as a template and characterized by transmission electron microscopy, X-ray diffraction, thermogravimetry and electrochemical measurement. As anode materials for lithium ion battery, they present eximious kinetic performance and good capacity retention due to their special architecture with mesoporous channels and thin walls, which are beneficial to the diffusion of lithium ions. Besides, mixing 3D ordered mesoporous titania microparticles with conductive additive can reduce the resistance of the anode, favor the mobility of the electrons, and decrease the polarization.
