| titleOfInvention | Phenolic resin/sucrose-based hard carbon microsphere material, preparation method thereof and sodium ion battery |
| abstract | The invention relates to the technical field of sodium ion batteries, and provides a preparation method of a phenolic resin/sucrose-based hard carbon microsphere material. According to the invention, phenolic resin, sucrose and a solvent are mixed for solvothermal reaction, rich functional groups of the sucrose and the phenolic resin are utilized, in the solvothermal reaction process, the long chain structure of the phenolic resin is rearranged, the hydroxyl in the sucrose and the unsaturated group in the phenolic resin are subjected to cross-linking reaction, the product is slowly crystallized to obtain spherical particles with smooth surfaces, and then the spherical particles are subjected to high-temperature carbonization treatment to obtain the hard carbon material with the spherical structure. Experimental results show that the hard carbon material provided by the invention is used as a cathode of a sodium ion battery, so that the high initial coulombic efficiency and the high cycling stability are maintained, and meanwhile, the reversible capacity is high. |
