Product Overview of Carboxymethyl Cellulose (CMC)

Carboxymethyl Cellulose (CMC) Micron Powder is a high-purity, cellulose-derived polymer material with a purity of ≥99.5%, designed for research and development of lithium-ion battery anode formulations. Supplied as a white powder, this material exhibits a viscosity of 7,000–10,000 mPa·s in a 2% aqueous solution, a degree of substitution of 0.6–0.9, and a pH range of 6.0–8.5.

CMC is widely used as a water-based binder and rheology modifier in lithium-ion battery electrode manufacturing. Its thickening and binding characteristics help control slurry viscosity, support the dispersion of active materials, and contribute to electrode coating uniformity. It is commonly investigated in graphite-based and silicon-containing anode formulations, often in combination with styrene-butadiene rubber (SBR) binders.

As a water-processable polymer additive, CMC supports research into aqueous electrode processing and alternative binder systems. Its effectiveness depends on electrode composition, binder concentration, slurry preparation conditions, and electrochemical testing parameters.
