Abstract

Flower-like LiMnPO4 nanostructures self-assembled with nanobelts were synthesized via a simple ethylene glycol (EG) solvothermal route, in which lithium acetate, manganese acetate and phosphoric acid are used as the reaction precursors. The primary block LiMnPO4 nanobelts are dominated with (010) facets. X-ray diffraction, scanning electron microscopy, transmission electron microscopy (TEM), high-resolution TEM, and N2-physisorption technique were employed to characterize the microstructure and morphologies of the synthesized samples. On the basis of the experimental results, a possible formation mechanism of the flower-like LiMnPO4 nanostructures self-assembled with nanobelts has been discussed. In addition, the electrochemical performance of the mesoporous LiMnPO4 nanostructures is further investigated as positive cathodes in Li-ion batteries.
