▎ 摘　　要

NOVELTY - The method involves complicating process of thermochemical purification of graphite relatively and is performed necessary to comprehensively consider the components of the exhaust gas. The organic matter and binders on the surface of waste lithium-ion electrode materials are removed through pyrolysis to improve the flotation and separation efficiency of positive and negative electrode materials for waste lithium-ion batteries. The organic matter and binders are used as a graphene raw material since the regenerated graphite maintains the original graphite lattice. The regenerated graphite is used to prepare graphene, first treat the regenerated graphite with phosphorus pentoxide (P2O5), potassium persulfate (K2S2O8) and concentrated sulfuric acid (H2SO4), and the product with concentrated H2SO4, potassium permanganate (KMnO4)and hydrogen peroxide (H2O2) are treated to generate oxygen-containing graphite products. USE - Tail gas treatment method for production of lithium-ion battery graphite anode material used for lithium ion battery. ADVANTAGE - The method enables to produce graphite material negative electrode lithium ion battery, which has high chemical absorption efficiency, high quality and high yield recycling waste of the waste lithium ion ion battery negative electrode high temperature removing organic matter. The method adopts special spiral condensing device, the heat exchange time is long, the condensing effect is good, the metal simple substance is condensed and collected, and two sets of devices are installed in parallel. The method realizes online cleaning. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating an tail gas treatment method for production of lithium-ion battery graphite anode material.
