Abstract
The invention discloses the reprocessing of the byproduct graphite powder in a kind of production of silicon carbide to utilize method, this method is that the graphite powder for generating silicon carbide in process of production is fitted into pincers pot, it places into resistance furnace and is electrically heated, temperature is maintained at 2600 DEG C -3000 DEG C and is purified, purification time 72-120 hours is taken out later.Graphite powder by purification is the negative electrode material of new energy dynamic lithium battery, lithium ion battery is a kind of environmentally friendly high-performance renewable energy, be mainly used for mobile phone, laptop, video camera, communication apparatus, automobile and the electromechanical industries of IT industry, wherein especially with electric vehicle apply for the electrical source of power field of representative it is with the fastest developing speed.The present invention silicon carbide can be produced in byproduct graphite powder by smelting furnace resistance furnace high temperature purification, just become new energy dynamic lithium battery negative electrode material, ink powder utility value substantially increases, and has not only met the demand in market, but also reduces pollution on the environment.
Description
Technical field
The present invention relates to silicon carbide smelting field, byproduct graphite powder in specifically a kind of silicon carbide production again plus
Work utilizes method.
Background technique
Graphite powder be silicon carbide production in byproduct, in the past be used as waste disposal, two or three one hundred yuan per ton, processing difficulty
Greatly, it is stacked upon and pollutes the environment.
Summary of the invention
In conclusion it is an object of the invention to disclose the reprocessing benefit of the byproduct graphite powder in a kind of production of silicon carbide
Use method.
The reprocessing of byproduct graphite powder in a kind of production of silicon carbide utilizes method, and its step are as follows:
A, the graphite powder for generating silicon carbide in process of production is fitted into pincers pot, is placed into resistance furnace and is electrically heated, temperature
Degree is maintained at 2600 DEG C -3000 DEG C and is purified, and purifies time 72-120 hours, takes out later.
Graphite powder by purification is the negative electrode material of new energy dynamic lithium battery, and lithium ion battery is a kind of environmental-friendly
Type high-performance renewable energy is mainly used for mobile phone, laptop, video camera, communication apparatus, the automobile of IT industry
And electromechanical industries, wherein especially with electric vehicle apply for the electrical source of power field of representative it is with the fastest developing speed.Lithium ion battery be by
Electrode (anode/cathode) material, diaphragm and electrolyte are constituted, the currently used mainly different stones of lithium ion battery negative material
The graphite type material of Mo Huadu, including modified natural graphite, artificial graphite and composite graphite.In the past, the lithium ion battery in China
Graphite negative electrodes material depends on import, and especially from Japanese import, this seriously constrains Chinese lithium ion battery industry
Development.Currently, the country, China only has Very few companies to be able to produce lithium ion battery negative material --- carbon graphite material.
Advantages of the present invention and the utility model has the advantages that
The present invention provides the reprocessing of the byproduct graphite powder in a kind of production of silicon carbide using method, can produce silicon carbide
Byproduct graphite powder pass through smelting furnace resistance furnace high temperature purification, just become new energy dynamic lithium battery negative electrode material, market
Ten thousand yuan of valence 5-6 per ton.So, the graphite powder utility value of silicon carbide producer substantially increases, and no longer regards waste product
It handles, has not only met the demand in market, but also reduce pollution on the environment.With economic construction of China and science and techniques of defence
The dosage of the quickening of developing steps, lithium battery is increasing, and the demand to lithium cell cathode material also obviously increases, according to a preliminary estimate
Growth rate in recent years can maintain 40 ~ 50% or so, and lithium cell cathode material market prospects are boundless.
