| titleOfInvention | A kind of preparation method and application of nitrogen and sulfur doped porous hollow carbon spheres |
| abstract | The invention relates to the technical field of negative electrode materials for lithium ion batteries, and discloses a porous hollow carbon sphere doped with nitrogen and sulfur. As the negative electrode active material of lithium ion batteries, the porous hollow carbon spheres doped with nitrogen and sulfur have a unique porous and hollow structure , the specific surface area is larger, the pore structure is rich, the diffusion path of lithium ions is shortened, and the extraction and intercalation of lithium ions are promoted, thereby improving the actual specific capacity of the negative electrode material, and nitrogen is doped in porous hollow carbon spheres with pyrrole nitrogen, The existence of pyridinic nitrogen and graphitic nitrogen improves the electrochemical properties of porous hollow carbon spheres, has higher electronic conductivity and conductivity, and improves the rate performance of negative electrode materials, while sulfur doping is beneficial to expand the carbon layer spacing, The pore structure and specific surface area of porous hollow carbon spheres are further improved, so that the lithium ion deintercalation sites are more fully exposed, and the lithium storage performance is more excellent. |
