Abstract:

A composite of TiO2 and MgO-templated disordered mesoporous carbon was prepared through infiltrating precursor solution (titanium isopropoxide) into the carbon matrix and growing TiO2 nanocrystals in the pore of the carbon. Transmission electron microscope (TEM) and scanning electron microscope (SEM) image showed that TiO2 nanoparticles are embedded homogeneously in the mesoporous carbon matrix without formation of big particles out of the pores or agglomeration. The electrochemical properties were evaluated by galvanostatic charge/discharge cycling. The composite electrode material showed excellent high-rate characteristics and cycling stability. Uniform dispersion of the TiO2 nanoparticles over the carbon matrix is believed to enhance the electronic conductivity and Li+ ion diffusion of the composite electrode material and thus result in good rate capability.
