| titleOfInvention | A kind of preparation method of high graphitization degree carbon-based material for lithium battery negative electrode |
| abstract | The invention discloses a preparation method of a carbon-based material with a high degree of graphitization for a negative electrode of a lithium battery, comprising the following steps: placing melamine or urea in a porcelain boat, filling the powder, sealing with a cover, and placing it in a muffle furnace , heat up slowly to obtain carbon nitride powder; dissolve the soluble salt of iron, cobalt and nickel in an appropriate amount of water to obtain a clear solution; put the carbon nitride powder in water, stir to form a suspension, and add the clear solution dropwise, After stirring, suction filtration, drying, and treatment to obtain catalyst/carbon nitride powder; the solid pitch is crushed into pitch powder, and the liquid heavy oil residue precursor is not treated; the catalyst/carbon nitride powder and pitch powder are directly Solid state mixing; placing the above-mentioned mixed material in a horizontal tube furnace, under an inert atmosphere, slowly heating up, and calcining at a constant temperature for 0.5-5h to obtain the product. The invention can obtain thin-layer porous carbon with high degree of graphitization, which not only has a large amount of graphite and high electrical conductivity, but also has a large number of cavities for lithium storage. |
