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. Recycling ›
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.

We would like to thank the VDI for the exciting article on our environmentally friendly recycling process for lithium-ion batteries.
As the CO2 savings from electromobility are intended to slow down global warming, we must not allow them to be cancelled out by improper recycling of batteries. In the environmentally friendly process from Duesenfeld, no CO2 is generated during mechanical recycling, and there are no toxic filter materials to be disposed of. 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 ›
With a 91% recycling rate at the battery cell level, i.e., without the battery casing and attachment systems, which often make up 50% of the total battery weight, the Duesenfeld process is the leader in battery recycling. Ecobalance ›
