FAQ
1、Is your Sodium Carboxymethyl Cellulose Powder (CMC) suitable for battery systems other than lithium battery anodes, such as sodium batteries or solid-state batteries? How would its performance differ in these different systems？
A:Thank you for your question! Our Sodium Carboxymethyl Cellulose powder is currently designed primarily for lithium battery anode slurries. Its viscosity of 7458mPa·s (in a 2% aqueous solution) and 99.7% purity effectively prevent active material sedimentation, ensuring stable slurry dispersion and improving electrode uniformity and battery longevity. For sodium batteries or solid-state batteries, although the basic principles are similar to lithium batteries, differences in electrolytes and active materials may require adjustments to parameters such as the viscosity and degree of substitution of the CMC. We recommend that you contact our technical support team before use, and we can provide customized solutions based on your specific needs.
2、How is the heavy metal content of your CMC powder tested? Can you provide relevant test reports? Also, how do you ensure the quality of the product is not affected during transportation?
A: We place great emphasis on product quality and safety. Our CMC powder is strictly produced in accordance with international standards. The heavy metal content (such as lead, iron, arsenic, etc.) is tested by professional laboratories to ensure compliance with industry standards (lead ≤15ppm, iron ≤40ppm, arsenic ≤2ppm). During transportation, we use sealed packaging and add desiccants inside to prevent moisture and contamination. At the same time, we choose reliable logistics partners to ensure that the product is not damaged during transportation. If any issues arise during transportation, we will handle them for you promptly
