Li₂MoO₄modified Li₂ZnTi₃O₈as a high property anode material for lithium ion battery

Lithium molybdate (Li₂MoO₄) modified Li₂ZnTi₃O₈has 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 Li₂ZnTi₃O₈modified by Li₂MoO₄(denoted as xLMO-LZTO) has a high specific capacity and rate property. Among the investigated samples, 12.12% Li₂MoO₄modified Li₂ZnTi₃O₈(12.12LMO-LZTO) has the best property. 12.12LMO-LZTO shows a first charge capacity of 267.5 mAh g⁻¹at 50 mAg⁻¹rate. In addition, it can also contribute 151 mAh g⁻¹at 1000 mA g⁻¹after 500 cycles, indicating excellent high rate and cycle performance. Li₂MoO₄modified Li₂ZnTi₃O₈has an outstanding electrochemical property can be attributed to the synergistic function of reducing particle size and the improving the electrochemical kinetics. Therefore, Li₂MoO₄modified Li₂ZnTi₃O₈anode material may become a new competitive anode material in place of the traditional anodes for lithium ion battery in the future.
