Additional Notes:
1. This product is suitable for use as a negative electrode binder for lithium-ion batteries.
2. Dissolve CMC in water with moderate stirring. Alternatively, pre-disperse CMC in a water-soluble solvent (such as ethanol or glycerol) and slowly add to water with moderate stirring.
3. It is recommended to store sealed in a well-ventilated, dry, dark, and cool environment to prevent moisture absorption.
