Abstract

The sub-micronmeteric Li4Ti5O12 powder material was successfully prepared through an improved solid-state synthesis process.The results of X-ray diffraction(XRD), scanning electron microscopy(SEM) and laser particle size distribution analysis showed that only a single spinel phase and a normal distribution pattern with the average size(D50) of 0.886μm could be observed. Due to the suitable partical size distribution, the Li4Ti5O12 powders showed a promising electrochemical performance. At the discharge current densities of 0.1C(16.5 mAh/g) and 5C, the discharge capacities reached 165 mAh/g and 107 mAh/g, respectively. Even at 10C, it still reached 54 mAh/g.
