| titleOfInvention | A kind of modified graphite and preparation method thereof, lithium battery negative electrode material, lithium battery negative electrode sheet and lithium battery |
| abstract | The invention provides a modified graphite and a preparation method thereof, a lithium battery negative electrode material, a lithium battery negative electrode sheet and a lithium battery. The preparation method of the modified graphite includes: oxidizing pretreated graphite to obtain pretreated graphite; The mixture of the treated graphite and the hydroxyl-containing polymer is subjected to complex reaction with zinc chloride, and then dried to obtain a precursor; the precursor is subjected to carbonization treatment to obtain modified graphite. In the invention, after oxidation pretreatment of graphite, the mixture of the graphite and the hydroxyl-containing polymer is complexed with zinc chloride, dried to obtain a gel-like precursor, and then the precursor is carbonized to obtain sp 2 +sp 3 amorphous Porous modified graphite with core-shell structure of carbon-coated sp2 graphite; the modified graphite provides a new way for electron conduction, lithium ion storage and electrolyte soaking in lithium batteries, and greatly improves the electrochemical performance of lithium batteries performance. |
