Carboxymethyl cellulose sodium (CMC2200)

This product is developed for use as a negative electrode binder in lithium-ion batteries, formulated from carboxymethyl cellulose sodium (CMC2200) with optimized physicochemical properties. It features low NaCl content, high purity, and a narrow molecular weight distribution, contributing to consistent viscosity and strong binding force. The material exhibits good hydrophilicity, stable solution viscosity over time, and excellent transparency and fluidity when dissolved. With a degree of substitution around 0.92 and a viscosity of 1750 mPa·s (1% aqueous solution, 25°C, 60 rpm), it balances dispersibility and processability. Recommended storage in sealed, dry, shaded conditions prevents moisture absorption. Typical applications involve dissolving in water with moderate stirring or pre-dispersing in a water-miscible solvent, making it suitable for slurry preparation in battery electrode manufacturing.

1. This product is suitable for negative electrode binder of lithium-ion batteries.

2. Dissolve CMC in water with moderate stirring, or disperse CMC in a solvent dissolved in water (such as ethanol, glycerol, etc.) and slowly add it to water with moderate stirring.

3. It is recommended to store in a sealed, well-ventilated, dry, and shaded environment to prevent water absorption.
