Optimized Hydrothermal Synthesis of LiFePO4-C Composites for Rechargeable Lithium Batteries |
| 초록 |
LiFePO4-C composites were synthesized by a hydrothermal method and subsequent high-energy ball-milling. Different carbon conductive additives including nano-sized acetylene black and multi-walled carbon nanotube (MWCNT) were used to enhance the electronic conductivity of LiFePO4. The structural and morphological performance of LiFePO4-C composites was investigated by X-ray diffraction (XRD) and scanning electron microscopy. The electrochemical properties of Li/LiFePO4-C batteries were analyzed by cyclic voltammetry and charge/discharge tests. XRD results demonstrate that LiFePO4-C composites have an orthorhombic olivine-type structure with a space group of Pnma. Li/LiFePO4-C battery with 5 wt.% MWCNT displays the best electrochemical properties with a discharge capacity of 142 mAh g-1 at 0.25 C at room temperature. |
