摘要

NaLaTi_2O_6 nanosheet was achieved by one-step hydrothermal method and was reported for the first time as an anode material for lithium ion batteries. The phase structure and morphology analysis reveals that pure pervoskite NaLaTi_2O_6 possesses nanosheet morphology with thickness of about 20 nm and length of several hundred nanometers. The electrochemical performances demonstrate that NaLaTi_2O_6 has a good lithium ion insertion/extraction ability with a discharge capacity of about 180mAh/g, which is slightly larger than Li_4Ti_5O_(12) theoretical capacity (175mAh/g). Even more, after 1000 charge-discharge cycles at 100mA/g, it still maintains a discharge capacity of 165mAh/g, suggesting that NaLaTi_2O_6 could be explored as a potential anode material for lithium ion batteries.
