QIBEBT, LANXESS Collaborate on Lithium-ion Battery Separator
Professor CUI Guanglei, group lead of Biomimetics for Energy Storage at the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) launched a cooperation program with the Group Function Innovation & Technology, LANXESS Deutschland GmbH. The project, titled “New polymer fiber-based membranes for lithium-ion batteries”, has been officially initiated on April 15th, 2013.
The conventional polyolefin-based separators suffer from a poor thermal shrinkage at relatively high temperature above 90oC. This has raised serious concern over their ability to prevent internal electrical short circuit at these high temperature conditions.Through the collaboration, CUI’s research team will develop new polymer fiber-based membranes with high thermal stability, high electrochemical stability window and high ionic conductivity etc.The superior electrochemical performance of this new polymer fiber-based membranesat high temperature could make these nonwovens an alternative to polyolefin-based separators for high power or high temperature application.
The proposed 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.
