| description | The invention belongs to the field of lithium ion battery negative electrode materials, and relates to a high-compaction rate type lithium ion battery negative electrode material and a preparation method thereof. The lithium ion battery negative electrode material is obtained by performing graphitization after performing powdering, mixing, spheroidizing, modification and secondary spheroidizing on an artificial graphite raw material. The requirement on equipment is low, large-scale production is extremely easy, and determination shows that the prepared lithium ion battery negative electrode material has wide particle size distribution, high compaction density and good rate capability.
本发明属于锂离子电池负极材料领域，一种高压实倍率型锂离子电池负极材料及制备方法，通过对人造石墨原料制粉、混合、球化、改性和二次球化后进行石墨化，得到锂离子电池负极材料。对设备要求低，极易大规模生产，经测定，制备的锂离子电池负极材料具有粒度分布宽，压实密度高、倍率性能好。 |
