Effect of particle size and agglomeration of TiO2 on synthesis and electrochemical properties of Li4Ti5O12

摘要：

The effects of the initial condition of synthesis on electrochemical properties of Li4Ti5O12 were studied with the comparison among starting and final materials by SEM,XRD and electrochemical analysis methods.The influence of the solvents for mixing the starting material on the products was investigated.The results show that nano-sized Li4Ti5O12 powder obtained by nano-sized TiO2 with ethanolamine as solvent shows more excellent electrochemical performance.More than 95％,91％,85％ and 71％ of the nominal capacity is achieved respectively at 0.5C,1C,2C and 4C rate without excellent capacity fading after more than 30 cycles.
