微晶石墨是一种天然石墨，现有的工艺在制造锂电池时均利用人造石墨进行生产，但是人造石墨具有成品率低，成本高等问题，而且一般的提纯工艺都是采用化学方式进行提纯，因此有环境污染大、成本高等不足，制作出来的锂电池负极的电容量不高，放电充电次数也非常低。
发明内容
为了克服现有技术的上述缺点，本发明提供一种利用高纯微晶石墨生产锂电池及增碳剂的生产方法，它能够代替人造石墨和鳞片石墨进行生产之用，同时具有绿色环保、成本低、制作出来的电池负极电容量大、使用周期长等特点。
本发明解决其技术问题所采用的技术方案是：一种利用高纯微晶石墨生产锂电池及增碳剂的生产方法，其生产步骤是：
选取碳含量为80%以上的微晶石墨，将微晶石墨送入造粒机中压制成型，成型后再将圆柱体或方形的石墨送入回转炉内并投入粘接剂和火碱，制得相应的成品，再将成品进行筛分，大块固体则作为电池负极材料送入石墨化炉内并等距摆放，细小的颗粒筛选出来放在电池负极材料之间的间隙内。
在所述石墨化炉的四周填充入无烟煤作为保温料。
本发明的积极效果是：它能够代替人造石墨和鳞片石墨进行生产之用，同时具有绿色环保、成本低、制作出来的电池负极电容量大、使用周期长等特点。
附图说明
