Project funded by FEDER Hauts-de-France
These batteries use an advanced polyanionic technology, NVPF (Na3V2(PO4)2F3), requiring appropriate recycling solutions.
In collaboration with Tiamat, Mecaware is developing an innovative chemical process to extract strategic metals, notably vanadium, from production scrap. The aim is to close the loop of the circular economy by reintegrating these recycled materials into the synthesis of cathode active material (CAM), then into the manufacture of new sodium-ion battery cells.
The NaCRe project builds on a successful proof-of-concept from the SEPAR8 Process project, winner of the FTJ Hauts-de-France grant. This previous project demonstrated the feasibility of recycling active cathode materials from Na-ion cells, confirming the potential of this recycling technology to reduce the environmental impact of battery production.
With NaCRe, Mecaware strengthens its commitment to recycling new-generation batteries, contributing to a sustainable energy transition and securing supplies of strategic metals in Europe.

Project launch
Validation of a process suitable for recycling cathode scraps
Validation of a recycling process adapted to cell scraps, a waste product representative of real-life conditions at the Tiamat gigafactory.
Transposition of the process to Mecaware's Vénissieux Demonstrator and TRL 5 achievement
Validated protocol for synthesizing active ingredients from recycled metals
Prototyping Na-ion cells with recycled content
The project will conclude with the completion of technical and economic studies and a life cycle assessment of the process to demonstrate the benefits of incorporating recycled material into cell production.

Mecaware is an industrial start-up specialising in the production of recycled strategic metals from Gigafactory scrap and end-of-life batteries.
Role in the project: Mecaware is responsible for the development of the innovative recycling brick and the production of metal salts from Tiamat's Na-ion battery waste.
Gigafactory for sodium-ion batteries, located in Amiens, in the Hauts-de-France region. A world pioneer in the production of lithium- and cobalt-free batteries, Tiamat innovates for a more sustainable future.
Role in project : Qualify and quantify your production waste, feed it into the recycling process and synthesise active materials and cells from recycled materials.
