Cellulose Separator
Product Description
Cellulose, a promising material known for its natural abundance, biocompatibility, and renewability, has been extensively used for centuries across various application fields. It has also emerged as a potential alternative to conventional polyolefin separators in lithium-ion batteries due to its plentiful sources, lightweight, superior electrolyte wettability, and enhanced thermal stability compared to some polymer materials. Research on cellulose-based separators for batteries has been widely reported in recent years. As a leading supplier of battery materials, our company is committed to providing you with high performance cellulose separator. If our product piques your interest, please do not hesitate to contact us.

You Need to Know
Our product is made of cellulose and therefore tends to absorb moisture and may contain 7-10% moisture depending on the circumstances. Therefore, ensure that the product is thoroughly dried before use. The recommended drying conditions are vacuum drying at 100-160°C for 24 hours. After the drying procedure, please handle our product in a low dew point environment. It is recommended that the dew point be below -60°C. In addition, please note that our product may experience longitudinal and transverse shrinkage of about 1% during the drying process.
