In the field of LITHIUM ion battery, preparation method of negative electrode slurry and PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC. In the preparation of aqueous negative slurry for lithium ion batteries, Jun methyl cellulose steel (CMC) is generally used as a thickening agent for slurry to prevent slurry settling during the preparation and coating process.
Since Jun methyl cellulose steel is a natural hydrophilic substance, the Jun methyl cellulose steel particles dispersed in the deionizing water will immediately swell and then gradually dissolve naturally to form a jelly-like Jun methyl cellulose steel gel solution. However, due to the swelling of Jun methyl cellulose steel after water absorption, and the strong viscosity between the particles, the agglomeration and agglomeration of Jun methyl cellulose steel will be formed. PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC field removal of iron
Therefore, in the preparation process of the water-based negative slurry after iron removal by PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC, it is necessary to "glue" the Jun methyl cellulose steel first, that is, add the solid particles of Jun methyl cellulose steel to the delithium ion water according to a certain ratio. Then a strong mixing machine is used for mixing the glue solution.
