| titleOfInvention | A kind of processing preparation method for lithium ion hard carbon negative electrode material |
| abstract | The invention discloses a processing and preparation method for a lithium ion hard carbon negative electrode material, including step 1, raw material treatment; step 2, precursor preparation; step 3, pre-sintering and pulverization; step 4, coating pyrolysis; wherein In the above-mentioned step 1, graphite, coal, wood or thermoplastic resin containing carbon elements are selected as raw materials, and the raw materials are cleaned and dried to obtain dry raw materials; wherein in the above-mentioned step 2, the thermoplastic resin is cured in the air at room temperature for 5~ 45h, a solid precursor was obtained; due to the high capacity, low cost and excellent cycle performance of hard carbon due to its random ordering, hard carbon was prepared as a negative electrode material, which improved the capacity of the battery and facilitated its use; in the hard carbon negative electrode In the preparation process of the material, a small amount of carbon dioxide is introduced to consume the carbon material, so that the carbon lattice of the prepared hard carbon negative electrode material is short-range ordered and long-range disordered, and the chemical properties of the hard carbon negative electrode material are improved. |
