Dry-processed electrodes that do not require expensive and sometimes toxic solvents and instead use polytetrafluoroethylene as a binder could make battery cell production more environmentally friendly and cost-effective.<\/p>\n

A research team from the MEET Battery Research Center and the Institute of Business Chemistry at the University of M\u00fcnster has now developed a method for recycling such dry-processed cathodes\u2014an important step toward circular batteries.<\/p>\n

Innovative production processes such as dry electrode processing are a crucial milestone toward a more environmentally friendly and cost-effective battery cell production. This app<\/a>roach completely avoids the use of expensive and partly toxic organic solvents, achieved by selecting the appropriate binder: the high-temperature plastic polytetrafluoroethylene (PTFE).<\/p>\n

To strengthen the circular economy of batteries with such processes, it is essential to integrate recycling possibilities from the very beginning. A team from MEET Battery Research Center and the Institute of Business Chemistry at the University of M\u00fcnster has therefore developed a method for the scrap recycling of dry-processed lithium ion battery cathodes.<\/p>\n

The results<\/a> have been published in the journal Advanced Energy Materials<\/i>.<\/p>\n

“The recycling can be successfully implemented and scaled up dry mechanically using mills,” says Maike Michelle Gnutzmann, Ph.D. student at MEET Battery Research Center and International Graduate School BACCARA.<\/p>\n

For dry-processed cathodes, the mills separate the cathode composite from the current collector and granulate it. As a result, all components, such as active material, PTFE binder and conductive carbon black, are available in their original form.<\/p>\n

“Since the materials involved are not degraded by the recycling process, they can be directly reused,” says Maike Michelle Gnutzmann.<\/p>\n

In addition, the Institute of Business Chemistry evaluated the profitability of the procedure through a life cycle cost assessment (LCCA). The results show that the recycling process is attractive for industrial applications, not only for sustainability considerations but also for cost efficiency.<\/p>\n
