Description

A simple and an effective method for synthesizing high density, high capacity Li4Ti5O12 electrode material within a very short period of time, using homemade starch as carbon source is presented in this study.  Lithium Titanate (Li4Ti5O12/C) was synthesized by using a simple microwave assisted hydrothermal method, with LiCO3 and TiO2 as precursors in which different concentrations of homemade starch was employed as carbon source. The samples were characterized by three different techniques, namely powder X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and Energy Dispersive X-Ray (EDX). The results show mixed phase material containing Li4Ti5O12, TiO2 and Li2Ti3O7. The estimated particle size calculated using XRD results showed that the material produced were on the nanometer scale. It also showed that the sample with 5% starch produced the smallest particle size of 36.31 nm. The SEM images of the control sample (without starch) showed a flat continuous crystallite surface while that of the samples with starch showed discrete macron sized crystallites. The EDX spectra indicated that all the constituent elements were present.
