The recycling of lithium-ion batteries starts with the patented deep discharge of the batteries and the recovery of the energy. The deep discharge of the batteries using the Duesenfeld process ensures safe and efficient discharging of cells, modules or packs connected in series.

We would like to thank the VDI for the exciting article on our environmentally friendly recycling process for lithium-ion batteries.
With a recycling efficiency of more than 85% and material recovery rates exceeding 98%, the Duesenfeld process already exceeds all future requirements of the EU Battery Regulation 2023/1542. Licensing ›
The intelligent control system ensures optimal discharge performance. When a specified minimum voltage is reached, the battery is automatically short-circuited and can be safely removed from the series connection without interrupting the discharge process of the remaining batteries. Discharge ›
Using an innovative, mechanical recycling process, Duesenfeld has managed to recycle industrial cathode scrap in a pilot project and successfully use it directly in new batteries. In electrochemical test procedures, the cells with 26% recycled content and a discharge capacity of 162 mAh g-1, compared to 165 mAh g-1 for reference cells, were certified as having very good performance.

CO2 savings from electric mobility to slow down global warming must not be nullified by inappropriate recycling of the batteries. With Duesenfeld’s environmentally friendly process, no CO2 is generated during mechanical recycling. Recycling ›
As the only process in mechanical recycling, the Duesenfeld process requires no exhaust gas scrubbing. The plant and operating costs are halved. Thus no CO2 is generated and there are no toxic filter materials requiring disposal. Licensing ›
