tozero achieves industrial-scale graphite recovery for Li-ion batteries

Conventional recycling methods often result in graphite being burned or lost to waste streams due to the use of strong acids, preventing its efficient recovery. However, tozero’s innovative process achieves more than 80% graphite recovery while preserving its morphological integrity on an industrial scale. This breakthrough enables the material to be refined back to battery-grade quality. The successful cell test showcases comparable performance to a battery cell made out of virgin graphite.

This milestone highlights the potential to integrate recycled graphite into global supply chains, reducing carbon emissions, accelerating the electric transition, and ensuring the true circularity of battery materials. This was made possible through dedicated efforts and collaboration, further validating the potential of recycled materials in the battery industry.

Sarah Fleischer, Co-Founder and CEO of tozero, said: “This is a milestone not just for tozero, but for Europe’s battery industry as a whole. We’ve already seen our recycled lithium successfully re-enter Europe’s supply chain, and now we’re proving the same for graphite. Despite being essential for battery stability, graphite is often overlooked in recycling – largely seen as unrecoverable – yet it is even more critical and geopolitically exposed than lithium.

With our FOAK plant on track, we’re scaling to recover even more critical materials, helping companies worldwide decarbonise, secure local supply chains, and move towards true circularity – bringing lithium-ion battery waste to zero.”

Scaling recycled graphite for a secure and sustainable battery supply chain

The rapid expansion in EVs and the growing need for large-scale renewable energy storage to combat the climate crisis is driving an unprecedented surge in demand for critical materials for batteries including graphite. In the EU alone, graphite demand is expected to rise by 20-25 times current levels by 2040 in the race to reach net zero, unachievable by current levels.

Currently, 98% of Europe’s graphite is imported, with China controlling over 90% of global supply, leaving battery manufacturers vulnerable to trade restrictions and supply chain disruptions. Looking into 2030, almost 800,000 metric tonnes of graphite supply gap worldwide remains to be filled. In addition, graphite alone accounts for over 10%-40% of a battery’s total carbon footprint, with natural graphite mining remaining environmentally costly, contributing to deforestation, water contamination, and high carbon emissions. However, this presents a strategic opportunity to shift toward sustainable, locally sourced, and circular solutions.

To address these challenges, battery and car manufacturers are increasingly turning to recycled graphite – not just for supply chain resilience, but also to comply with new regulations like the EU Battery Directive, European Critical Raw Material Act, and meet their net zero targets. This makes scaling high-quality, battery-grade recycled graphite essential to reducing dependency on imports, cutting emissions, and securing a stable, circular supply chain for the future of clean energy.
