The Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) and LANXESS Deutschland GmbH launched a cooperation program “New Polymer Fiber-based Membranes for Lithium-ion Batteries” on April 15, 2013.
The program aims at developing new polymer fiber-based membranes with high thermal stability, high electrochemical stability window and high ionic conductivity etc. The conventional polyolefin-based separators suffer from poor thermal shrinkage at relatively high temperature above 90℃. This has raised serious concern over their ability to prevent internal electrical short circuit at high temperature conditions.
The superior electrochemical performance of new polymer fiber-based membranes at high temperature could make these nonwovens an alternative to polyolefin-based separators for high power or high temperature application.
The objective of this project combines QIBEBT’s expertise in high performance separators for the next generation lithium-ion battery and LANXESS products on high performance polymer.
LANXESS is a leading specialty chemicals company with sales of EUR 8.8 billion (~71 billion CNY) in 2011 and currently around 17,100 employees in 31 countries. The company is currently represented at 48 production sites worldwide. The core business of LANXESS is developing, manufacturing and marketing plastics, rubber, intermediates and specialty chemicals.
