Research & Development

We conduct research. For your business. And our environment.

We have a clear vision: We want to process and recycle used cells to produce new batteries. Our goal is to achieve zero waste.


We closely collaborate with universities, research institutes and industrial partners. Our extensive research and development activities are conducted with a clear focus on batteries enabling us to noticeably advance and continuously improve technological development in recycling.


Our research activities show clear results.

Successful research:

  • Redux holds numerous patents, including a patent for an X-ray sorting process that helps us achieve a sorting accuracy of up to 99%.
  • In April 2015, we collaborated with Energizerm one of the world's largest manufacturers of batteries. Together we managed to launch “EcoAdvanced” batteries that were produced by reusing battery components recycled by Redux.
  • Our self-developed sorting process proved particularly efficient and enables us to sort up to 40 batteries per second.
  • A key element of our research activity is maximum protection of the environment. Therefore our plants are certified according to ISO 9001 and ISO 14001. These certifications guarantee highest quality standards.
  • Thanks to our proprietary lithium-ion battery processing method, we are capable of achieving high metal recycling rates. The active mass produced by us contains highly concentrated nickel, cobalt and lithium, and is produced according to international standards.

Current research projects

New procedures for the recovery of valuable materials from batteries.
Saubermacher and Redux are collaborating with other parties on the EU-funded ‘Crocodile’ research project. The project seeks to develop and test new procedures for the recovery of valuable materials from batteries, such as cobalt and nickel. This would see the recycling rate of lithium-ion batteries increase further, and help to improve the quality of the recycled material.

Further information

This project has received funding from the European Union's EU Framework Programme for Research and Innovation Horizon 2020 under Grant Agreement No 776473
The recycling of lithium-ion batteries produced high-grade active mass.
This research project is dedicated to improving the effectiveness of lithium-ion battery recycling. It seeks to provide insight into recycling steps, such as thermal treatment of batteries, and to deliver the boundary conditions for optimisation. In addition to improving the quality of recycled materials, such as cobalt and nickel, the project is also looking at the recovery of phosphorous and graphite, something which is not yet commonplace.
