| Preparation and Characterization of AlF3 Coated Natural Graphite Anode Materials |
|
| Abstract: AlF3 coated Natural graphite composite (AF/NG) was synthesized by high speed mechanical dispersion and spray drying with the natural graphite as raw material. On the one hand, a more stable SEI film can be formed with the help of AlF3, which promoting the cycle performance. on the other hand, the AlF3 can promote the diffusion of lithium ions between the particles, which is benefit to the rate capability. AF/NG delivered a reversible capacity more than 278 mAh·g-1 at 0.5C, with a capacity of 78 mAh·g-1 higher than the uncoated sample (NG). The synthetic process is easy to control which is suitable for large-scale commercial production. |
