| titleOfInvention | A kind of porous bismuth-carbon material, preparation method and application thereof |
| abstract | The invention provides a method for directly synthesizing a porous bismuth-carbon composite material by using bismuth oxycarbonate and magnesium. The method comprises the following steps: directly mixing bismuth oxycarbonate and magnesium powder evenly, placing them in a stainless steel reaction kettle, and 500 ℃ in an inert atmosphere. ℃ reaction to obtain the precursor, and then stirring and pickling in a tartaric acid solution until no obvious bubbles are generated to obtain the final porous bismuth-carbon product. The invention has wide material sources, simple method, green and pollution-free, and provides the possibility for large-scale production; the bismuth-carbon composite material prepared by this method has a porous skeleton structure, which can reduce the volume of the sodium-ion battery during the charging and discharging process. expansion, and the addition of carbon during the preparation process greatly improves the conductivity of the material; in the subsequent tests of sodium-ion batteries, it showed higher capacity and excellent rate performance and ultra-long cycle. stability. |
