Abstract
In this paper the effect of the structure, particle size, morphology of nanofibers and nanoparticles for the electrochemical characteristics of Li 4Ti5O12 was investigated. The H 2Ti2O5 · H2O synthesized in hydrothermal treatment from a NaOH treatment on TiO2 by ion exchange processing with HCl solutions. After the Li4Ti5O 12 nanofibers synthesized in hydrothermal treatment of H 2Ti2O5·H2O and LiOH·H2O. The hydrogen titanate precursor prepared by ion exchange processing with 0.1-0.3M HCl solutions and the final products calcined at 350°C-400°C. The Li4Ti5O12 nanofibers showed well reversibility during the insertion and extraction of Li, good cycle performance, high capacity and low electrochemical reaction resistance than nanoparticles. also c-rate exhibited a discharge capacity of 172mAh/g at 0.2C and H5mAh/g at 5C, which is the 77%, 67% ofthat obtained in the process charged, discharged at 0.2C.
