| 英文摘要 | A novel solvothermal approach with ascorbic acid as both an antioxidant and a first-time carbon coating source is developed to synthesize LiMn0.4Fe0.6PO4 nano-particles with a uniform particle size distribution around 150 nm. A calcination step for the second-time carbon coating and further crystallization is adopted following the solvothermal step. The structures and electrochemical properties of the obtained samples are studied by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, Raman spectroscopy, Fourier transformation infrared, Infrared carbon-sulfur analyzer and galvanostatic cell cycling. Ascorbic acid plays a crucial role in the formation of uniform carbon layer and nano-particles. Compared with single-carbon-coated LiMn0.4Fe0.6PO4 without adding ascorbic acid, the mixed-carbon-coated LiMn0.4Fe0.6PO4 shows much better electrochemical performance. It can deliver specific capacities of 154.8 and 128.5 mAh g(-1) at 1C and 20C, respectively, at 25 degrees C. Even at 20 degrees C, its specific capacities are 106.6 and 68.8 mAh g(-1) at 0.2C and 5C, respectively. (C) 2016 Elsevier Ltd. All rights reserved. |
