| Abstract: | Li4Ti5O12 has been widespread concerned because of the "zero strain" advantage during charge and discharge,it has been become a research focus as anode material for lithium-ion battery.In this paper,Li4Ti5O12 as anode material was prepared by solution method.The optimum preparation conditions were determined by orthogonal experiments: lithium titanate was heat-treated at 750 ℃ for 8 h,LiOH·H2O was selected as lithium source,the molar ratio of Li/Ti was 0.85.Li4Ti5O12 prepared at the optimum conditions had the better electrochemical performances,the initial discharge capacity reached 191.61 mAh/g. |
