Cylib & Vianode team up to close the battery graphite loop

German battery recycler Cylib and Norwegian materials specialist Vianode have signed an MOU to develop recycled graphite for next-generation batteries. The partnership targets a closed-loop supply chain for one of the EV industry's most critical raw materials.

What does it mean at home?

If the topic touches solar panels, storage, inverters or home EV charging, the right answer depends on consumption, roof area, orientation and future expansion together.

Zárt grafitkörkör: Cylib és Vianode összefog az akkuanyagokért

Cylib, a German battery recycling startup, and Vianode, a Norwegian battery materials company, have signed a memorandum of understanding to collaborate on graphite recycling. Their joint goal is to process and qualify graphite recovered from spent EV batteries for use in next-generation battery cells.

Why graphite matters for the EV supply chain

Graphite is a critical component of lithium-ion battery anodes and is classified as a critical raw material by the European Union. Currently, the vast majority of battery-grade graphite is sourced from China, creating a significant supply-chain vulnerability for European EV and battery manufacturers as demand accelerates.

The Cylib–Vianode collaboration aims to demonstrate that recycled graphite can meet the quality standards required for premium battery applications — effectively reducing dependence on virgin material imports. This aligns directly with the EU Battery Regulation, which sets increasing recycled-content targets for critical materials including graphite over the coming years.

From MOU to closed loop

The signed letter of intent marks the beginning of a testing and qualification phase, after which the partners will assess whether recycled graphite can be reintegrated into industrial-scale cell production. If successful, the project could serve as a template for circular material flows across Europe's rapidly expanding battery manufacturing ecosystem.
