Abstract
Abstract Lithium molybdate (Li 2 MoO 4 ) modified Li 2 ZnTi 3 O 8 has been firstly synthesized by the sol-gel method together with wet chemical method. Physical characterizations (XRD, SEM, TEM) and electrochemical methods (Cycle and rate performance, CV, EIS) have been used to analyze the structures, morphologies and electrochemical properties of the as-prepared materials. Compared to pure Li 2 ZnTi 3 O 8 (denoted as P-LZTO) anode material, the electrochemical properties show that the sample of Li 2 ZnTi 3 O 8 modified by Li 2 MoO 4 (denoted as xLMO-LZTO) has a high specific capacity and rate property. Among the investigated samples, 12.12% Li 2 MoO 4 modified Li 2 ZnTi 3 O 8 (12.12LMO-LZTO) has the best property. 12.12LMO-LZTO shows a first charge capacity of 267.5 mAh g −1 at 50 mAg −1 rate. In addition, it can also contribute 151 mAh g −1 at 1000 mA g −1 after 500 cycles, indicating excellent high rate and cycle performance. Li 2 MoO 4 modified Li 2 ZnTi 3 O 8 has an outstanding electrochemical property can be attributed to the synergistic function of reducing particle size and the improving the electrochemical kinetics. Therefore, Li 2 MoO 4 modified Li 2 ZnTi 3 O 8 anode material may become a new competitive anode material in place of the traditional anodes for lithium ion battery in the future.
