Carboxymethylcellulose (CMC), an anionic, linear, water-soluble cellulose ether, is a derivative of natural cellulose andChloroacetic acid through chemical modification. Its aqueous solution has the functions of thickening, film formation, adhesion,
water retention, colloid protection, emulsification and suspension.
1. The advised added quantity of CMC should be 1.2-1.5% of total powder.
2.The recommended concentration of CMC glue is 1.5-1.8%.
3.The stirring speed is 6-10m/S speed, and the stirring time is 90-150min. Long-term ultra-high-speed shear stirring is
As an anti-precipitation agent, it has a certain degree of cohesiveness. It is used in combination with SBR in lithium battery
negative electrode slurry to moisturize and stabilize negative electrode slurry.
