With artificial graphite as the negative active material, SP as the conductive agent, according to the mass ratio of graphite: SP:CMC:SBR= 94.0:1.5:2.0:2.5, solvent deionized water is 100% of the total amount of each component. PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC field preparation steps are as follows: Add thickening agent CMC into deionized water solvent, dissolve evenly with a mixer, take out and set aside for 60 minutes;
The negative active substance and conductive agent of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC magnetic removal of iron are added to the stirring bucket to stir and disperse, the time is 30 minutes, and the powder on the stirring paddle and the barrel body is scraped at the time of 15 minutes and 30 minutes; Add 55% of the total thickening agent solution to the stirred powder, stir and disperse for 60 minutes, and scrape the slurry on the mixing paddle and barrel body at the time of 20 minutes, 40 minutes and 60 minutes, and the slurry temperature is controlled between 25 and 35°C;
Add 35% of the total thickener solution to the high viscosity stirred slurry, stir and disperse for 60 minutes, and scrape the slurry on the stirring paddle and the barrel of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC at the time of 20 minutes, 40 minutes and 60 minutes. The temperature of the slurry is controlled between 25 and 35°C; The viscosity of the slurry stirred with low viscosity was tested, and the test result was 5332Mpa, exceeding the normal range value, 5% of the total solvent was added, and then stirred and dispersed for 30 minutes, and stirred at 15 minutes and 30 minutes.
