Li2MoO4 modified Li2ZnTi3O8 as a high property anode material for lithium ion battery
چکیده انگلیسی
Lithium molybdate (Li2MoO4) modified Li2ZnTi3O8 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 Li2ZnTi3O8 (denoted as P-LZTO) anode material, the electrochemical properties show that the sample of Li2ZnTi3O8 modified by Li2MoO4 (denoted as xLMO-LZTO) has a high specific capacity and rate property. Among the investigated samples, 12.12% Li2MoO4 modified Li2ZnTi3O8 (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. Li2MoO4 modified Li2ZnTi3O8 has an outstanding electrochemical property can be attributed to the synergistic function of reducing particle size and the improving the electrochemical kinetics. Therefore, Li2MoO4 modified Li2ZnTi3O8 anode material may become a new competitive anode material in place of the traditional anodes for lithium ion battery in the future.
