Abstract:	摘要： In this paper, we report on the solvothermal preparation of spindle-like LiMnPO4 assembled by nanorods with different crystallographic orientations and their electrochemical performance as the cathode materials of lithium-ion batteries. The crystallographic orientations of the nanorods were controlled via two synthetic routes with changed conditions. To improve the electric conductivity, the pristine LiMnPO4 has been carbon-coated by using sucrose as carbon source. The as-prepared LiMnPO4C nanorods have been applied as the cathode of Li-ion batteries, showing the discharge specific capacity of 153.5 mA h g-1 at 0.05 °C. The nanorods grown along the [010] direction have exhibited better electrochemical performance than that with a large number of (020) planes. The result shows that [010] orientation of olivine-structured LiMnPO4 is favorable for the improvement of the electrochemical properties. 出版者： American Scientific Publishers 出版日期： 2013-11-01 出處： Science of advanced materials, 2013-11, Vol.5 (11), p.1676-1685 識別號： ISSN: 1947-2935 識別號： EISSN: 1947-2943 識別號： DOI: 10.1166/sam.2013.1627
