| Popis: | In this paper, submicron Li2MoO4 material was synthesized via rheological phase method. The structure, composition and morphology of the obtained powders were characterized by X-ray diffraction (XRD), X-ray photoelectron spectrometer (XPS) and scanning electron microscope (SEM), respectively. The key calcination temperature was 700 oC. The particle sizes were about from 100 to 300 nm. As anode material of lithium ion batteries, lithium storage performances of the as-prepared Li2MoO4 were evaluated at different current densities. The best capacity retention was 75.7% of the initial capacity (592.13 mAh g-1) after 50 cycles at 0.2 mA cm-2 in 0.1-2.5 V, and the resistance was about 123.5 Ω, indicating a potential prospect in the application of lithium ions batteries. |
