Abstract

Nano-Li₄Ti₅O₁₂ pore microspheres were synthesized by hydrothermal and subsequent calcination methods using Ti-(OC₄H₉)4 and LiAc.2H₂O as raw materials. TEM analysis highlights the excellent crystallinity of the nano-sized Li4Ti5O12 primary particles with the size between 30-40 nm. As anode material of lithium ion batteries, the nano-Li₄Ti₅O₁₂ exhibits higher capacity and better rate capability, delivering the 1 C capacity close to the theoretical value of 175 mAh g^-1, 10C capacity of 133 mAh g^-1 and even 60 C capacity of 80 mAh g^-1. The ameliorated electrode-performance is ascribed to nanostructure of the material that provides shorter diffusion-paths and faster migration rate for both of ions and electrons.
