Abstract

The carbon modified Li4Ti5O12 was prepared by solid state reaction by using sucrose as carbon source.The XRD results showed that the incorporation of carbon did not change the spinel crystal structure of Li4Ti5O12 but it could prevent the particle agglomeration.The sample with 10%(by mass) sucrose displayed the best electrical performance,a 179.1 mAh/g of initial specific capacity was obtained at 0.2C,while 143.8 and 129.4 mAh/g at 2C and 3C,respectively.The CV and EIS studies revealed that carbon modification lowered the electrode polarization and electrode reaction resistance of Li4Ti5O12.
