Synthesis and Characterization of Li4Ti5O12 Prepared by Microwave Hydrothermal Method
Lithium titanate Li4Ti5O12 as lithium ion battery cathode material was synthesized using hydrothermal and microwave hydrothermal methods,the influencesof different methods on its electrochemical performance were examined,and its structure,morphology,constant cmrrent charge and discharge characterized.The results showed that Li4Ti5O12 could be synthesized by both methods,the latter could lead to better electrochemical properties of the sample in smaller and more uniform particle size and larger specific surface area,the first discharge capacity of 151.33 mA·h/g after 97 cycles was 140.94 mA·h/g,the capacity retention rate 93.14％,and the chemical impedance smaller.
