The preparation method of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC magnetic of negative slurry comprises the following steps: adding Jun methyl cellulose steel to the polyol and mixing well to obtain the first mixed liquid, wherein the mass ratio of the Jun methyl cellulose and the polyol is 1.5 ~2; 3. 5~4; Add the first mixture to the deionized water, mix well, and then stand for 3-5 hours to 4-5 hours to obtain the second mixture, in which the mass ratio of the deionized water and the first mixture is 3.21 to 4.75; 5 ~ 6;
PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC magnetic deionized water is added into the second mixture of iron removal and mixed well to obtain the mixed liquid, in which the mass ratio of deionized water and the second mixture is 5~ 6.44; 8.21 ~ 10.75; The conductive agent, negative active carbon material and benzene rubber emulsion adhesive were added to the mixture, and the negative slurry was obtained after mixing well. The mass ratio of the conductive agent, negative active carbon material, benzene rubber emulsion adhesive and the mixture was 1~ 1.5. 95.5 ~ 96.5; 4.15 ~ 4.5; 13. 21~ 17. 19.
Due to the large shear force of the high-speed dispersing mixer, the molecular chain of the Jun methyl cellulose steel is easily broken during the high-speed dispersing process, which will reduce the thickening property of the Jun methyl cellulose steel, resulting in a decrease in the storage and uniformity of the negative slurry prepared by PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC.
