Circu Li-ion, a leading European battery recycling startup, announces the successful closing of a €8.5 million seed financing round.

The recent funding includes €4.5 million in equity, which was led by BonVenture and saw additional backing from an undisclosed group of battery, AI, and industry experts, and a significant participation of the company’s management team. The investment is complemented by €4 million in grants from the EICA (European Innovation Council Accelerator) and collaborations with recyclers and OEMs — demonstrating their devotion to a greener future.

Circu Li-ion’s vision of bringing urban mining to life through an automated upcycling platform for end-of-life batteries is reinforced by the support and confidence of its new strategic partners. Contracts with market-leading OEMs from the Electronic Vehicles (EV), Micromobility, and Power Tools industries, alongside leading European recyclers, add invaluable expertise that will support Circu Li-ion’s further development. These partnerships highlight the collective goal of facilitating a circular battery value chain in Europe, especially considering the EV market's surge to become a trillion-dollar market by 2030.

Circu Li-ion holds a clear commitment to sustainability and recycling benchmarks with the ultimate goal of upcycling 3 billion batteries by 2035. Accordingly, the new funding will enable them to:

Enhance its Upcycling Platform

  • Machine-as-a-Service: Expanding rollouts to further European markets, Circu Li-ion’s Machine-as-a-Service product integrates advanced AI algorithms to optimize battery discharging, dismantling, disassembly, and diagnostics processes, reducing manual labor and minimizing environmental impact.
  • Disassembly-as-a-Service: Enabling clients to cleanly upcycle batteries on demand with Circu Li-ion’s certified facility in Karlsruhe, Germany.

Amplify its Proprietary Battery Data Library

  • Creating the World's Largest Battery Recycling Data Repository: By employing real-time data collection and analytical algorithms, Circu Li-ion won’t just house but also enable actionable insights from the world’s largest battery recycling data repository, thus facilitating data-driven decision-making across the platform.
  • Enabling a Battery Data Platform: Circu Li-ion’s data platform won't merely be a database but a holistic solution, offering access to a wealth of data points, predictive analytics, and strategic insights, revolutionizing recycling practices and material management.

Bolster Collaborations with EV OEMs and Recyclers

  • Bridging Recycling Gaps: The secured grants are strategically utilized to forge and expand collaborations with EV OEMs and recyclers, ensuring the integration of a circular approach in battery manufacturing, usage, and end-of-life processing, while pushing for sustainable practices throughout the battery lifecycle.
  • Sustainable R&D Partnerships: Circu Li-ion aims to co-create value by working closely with partners, involving them in product development and recycling initiatives, thereby ensuring that the solutions developed are in line with industry needs and contribute effectively towards building a robust circular battery economy.

Unlock New Capabilities in the Battery Recycling Value Chain

  • Battery Sorting: Utilizing AI, Circu Li-ion will elevate battery sorting standards as well as introduce an intelligent sorting system, improving accuracy and efficiency while reducing sorting times and ensuring maximal recovery of valuable materials.
  • Direct Recycling: Probing into material-level recycling, R&D will focus on developing innovative methodologies to segregate and process different battery components, potentially revolutionizing the recycling sector by minimizing waste and enhancing material reuse.

Expanding Circu Li-ion's main production facility to 2,000 m2

Alongside the company’s functional growth, Circu Li-ion plans to expand its main production facility near Karlsruhe, Germany to 2,000 m2 , while further growing its Berlin satellite office.


We're happy to double down on our development speed, turning this fresh funding into smarter, data-focused solutions that make battery recycling economically and ecologically viable for everyone. For this, the key is a great team – we will further invest in our team and double our size of currently 34 colleagues within the next twelve months.” Antoine Welter, CEO & Co-Founder Circu Li-ion


We are evolving our products with the agility and adaptability the swift-moving battery market demands. It's more than creating relevancy – it's about pioneering flexible solutions that carve out new possibilities for cleaner battery recycling.” Xavier Kohll, CTO & Co-Founder Circu Li-ion


Since the first contact with the outstanding team, we have been enthusiastic about the highly dynamic environment of battery up- and recycling in which they have occupied the field very early and taken a dominant role. Circu Li-Ion puts a stop to the current destruction of value in the form of a technically sophisticated and particularly innovative solution, thus unlocking previously inaccessible potential down to the level of the individual cell. This is what makes a particularly high level of sustainability possible in the first place and makes an important contribution to the transformation of many industries.” Nikolaj Klebert, Investment Manager, BonVenture
