Duesenfeld is a pioneer in the recycling of lithium-ion batteries and has developed processes that do not require the usual melting or heating of the battery modules at the beginning. Since the beginning, our processes have been environmentally friendly, the CO2 avoidance and the high recycling efficiency in the foreground.
As a spin-off of TU Braunschweig, Duesenfeld has entered into cooperation with other universities and research institutions such as TU Clausthal, and hydrometallurgical processes have been developed and patented from such cooperation arrangements. Further processes were developed directly at Duesenfeld and patented. The LitoRec recycling process is based on patents of Duesenfeld GmbH.
The Duesenfeld process with mechanical crushing of the batteries and further hydrometallurgical processing of the black mass is a low-temperature process. During the mechanical comminution and inactivation of the batteries, drying is carried out below 80 C and under vacuum only ...
