Method for recycling negative electrode graphite of waste lithium ion battery

The invention belongs to the technical field of lithium ion battery recovery, and discloses a method for recovering waste lithium ion battery negative electrode graphite, which comprises the following steps: mixing waste lithium ion battery negative electrode graphite, a composite starch binder and asphalt, adding water, carrying out wet mixing to obtain a coated wet material, preparing the coated wet material into a shape piece with the transverse size of 15-50mm, and drying to obtain the waste lithium ion battery negative electrode graphite. The preparation method comprises the following steps: performing carbonization treatment to obtain a graphite forming part, putting the graphite forming part into a vertical continuous graphitization furnace, sequentially performing low-temperature section and high-temperature section treatment of the vertical continuous graphitization furnace to obtain graphitized graphite, and crushing to obtain a graphite finished product. 本公开属于锂离子电池回收技术领域，公开了一种回收废旧锂离子电池负极石墨的方法，将废旧锂离
