We introduce a new synthesis method to prepare small TiO2 nanoparticles with a narrow particle size distribution, which is achieved by electron beam (E-beam) irradiation. The effects of E-beam irradiation on the synthesis of TiO2 nanoparticles and the electrochemical performance of TiO2 nanoparticles as alternative anode materials for Li-ion batteries are investigated. The TiO2 nanoparticles induced by E-beam irradiation present better cycling performance and rate capability than the TiO2 nanoparticles synthesized by normal hydrolysis reaction. The better electrochemical performance is attributed to small particle size and narrow particle size distribution, resulting in the large surface area that provides innumerable reaction sites and short diffusion length for Li+ through TiO2 nanoparticles.
