titleOfInvention | Ternary positive electrode slurry, preparation method thereof and lithium battery |
abstract | The invention discloses ternary cathode slurry, a preparation method thereof and a lithium battery. The method comprises the following steps: (1) mixing a ternary precursor material with a lithium source, sintering to obtain a ternary cathode material, and mixing the ternary cathode material with a conductive agent to form a material M1; (2) mixing a binder with a defoaming agent to form a material M2; (3) and melting and mixing the material M1 and the material M2 to obtain the ternary cathode slurry. The preparation method provided by the invention leads the adhesive to form a uniform colloidal mixture by melt mixing; when a double-screw extruder is used, the ternary cathode material, the conductive agent and the current collector can be organically combined, and a close interface contact and an electron transfer channel are formed among the ternary cathode material, the conductive agent and the current collector; the defoaming agent is used for eliminating the surface tension of each material to eliminate micro air holes, so that the system is further compact; when the graphene conductive agent is used, the energy density of the product prepared into the lithium battery can be further improved. |
