| titleOfInvention | Preparation method and product of composite negative electrode material, negative electrode sheet and secondary battery |
| abstract | The invention provides a preparation method and product of a composite negative electrode material, a negative electrode sheet and a secondary battery, comprising the following steps: S1, mixing and modifying carbon nanotubes and a cationic surfactant, and taking the carbon nanotube solution in the upper layer; S2. The carbon nanotube solution obtained in step S1 is transported at a constant speed to the graphene oxide aqueous solution for electrostatic self-assembly, and after the reaction, a reducing agent is added to carry out a thermal reaction to obtain a precipitate, which is washed and dried to obtain a composite negative electrode material RGO/CNT . Compared with the prior art, the composite negative electrode material provided by the present invention effectively solves the problem that the current graphene as an electrode material is prone to stacking, which makes it difficult to intercalate lithium ions, and effectively improves the gram capacity and cycle performance of the battery. |
