Abstract

ABSTRACT We introduce a new synthesis method to prepare small TiO 2 nanoparticles with a narrow particle size distribution, whichis achieved by electron beam (E-beam) irradiation. The effects of E-beam irradiation on the synthesis of TiO 2 nanoparticlesand the electrochemical performance of TiO 2 nanoparticles as alternative anode materials for Li-ion batteries are investi-gated. The TiO 2 nanoparticles induced by E-beam irradiation present better cycling performance and rate capability thanthe TiO 2 nanoparticles synthesized by normal hydrolysis reaction. The better electrochemical performance is attributed tosmall particle size and narrow particle size distribution, resulting in the large surface area that provides innumerable reacti onsites and short diffusion length for Li + through TiO 2 nanoparticles.Keywords : TiO 2 , nanoparticle, electron beam irradiation, anode material, Li-ion battery Received October 23, 2014 : Accepted January 27, 2015 1.
