Resumo |
A MoO<sub>3</sub>-carbon nanocomposite was synthesized from a mixture of MoO<sub>3</sub> and graphite by a controlled ball milling procedure. The as-prepared product consists of nanosized MoO<sub>3</sub> particles (2-180 nm) homogeneously distributed in carbon matrix. The nanocomposite acts as a high capacity anode material for lithium-ion batteries and exhibits good cyclic behavior. Its initial capacity exceeds the theoretical capacity of 745 mA h g<sup>-1</sup> in a mixture of MoO<sub>3</sub> and graphite (1:1 by weight), and the stable capacity of 700 mA h g<sup>-1</sup> (94% of the theoretical capacity) is still retained after 120 cycles. The electrode performance is linked with the unique nanoarchitecture of the composite and is compared with the performance of MoO<sub>3</sub>-based anode materials reported in the literature previously (nanoparticles, ball milled powders, and carbon-coated nanobelts). The high value of capacity and good cyclic stability of MoO<sub>3</sub>-carbon nanocomposite are attractive in respect to those of the reported MoO<sub>3</sub> electrodes.<br /> |
