Our Vision

Fighting the climate crisis by maximising the lifecycle of each Li-ion cell. 


There is significant CO2 reduction potential in automated battery upcycling.
Used batteries are a true resource - more than 80% can be recovered when a battery is at the end of its first life.

Therefore, we have designed a machine to extract and diagnose the cells in an automated manner from their battery packs and enable their reusage
Today, there are solutions to give batteries a second life, for example as an energy storage. This implies a first downgrade as the batteries stay with limited capacity (REUSE).
Other recycling methods are inefficient as they shred and melt the entire battery pack including its still functioning parts in an energy intensive process. The resulting raw materials can be recycled (RECYCLE).

Our Technology

Our process sets new technological and ecological standards, closing the loop and fully enabling the circular economy in the battery industry.

The automated processing line starts with the diagnostics of the battery packs, followed by the disassembling step, down to the cell level and the diagnostic of each cell.

Given our modular set-up, the line can then proceed to re-assembling the cells into energy storage solutions like a battery pack, grid storage, etc.


Current battery lifecycle

Currently, batteries including their still functional parts are destroyed and the remaining raw materials are used to make new batteries from scratch.
