Good stability cheap price sodium carboxymethyl cellulose cmc powder for lithium battery binder
Carboxymethylcellulose (CMC), an anionic, linear, water-soluble cellulose ether, is a derivative of natural cellulose and chloroacetic acid through chemical modification. Its aqueous solution has the functions of thickening, film formation, adhesion,water retention, colloid protection, emulsification and suspension.
Application:
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.
Use Tips:
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 strictly prohibited.
