Description
Carboxymethyl Cellulose (CMC) Micron Powder for Li-ion Battery Anode Materials
Carboxymethyl Cellulose (CMC) is a high-purity white micron powder widely used as a thickening agent and anti-precipitant in the formulation of lithium-ion battery anode slurries. Its excellent water solubility, stable viscosity, and effective binding properties make it an ideal additive in the preparation of graphite-based and other carbonaceous anode materials.
As a binder and dispersant, battery-grade CMC ensures uniform distribution of active materials, enhances slurry stability, and improves the mechanical strength of the electrode film. It also helps reduce material sedimentation during coating, ultimately contributing to improved battery performance, longer cycle life, and consistent production quality.
