Company Overview

CarbonX, founded in 2014 as a spin-off from Delft University of Technology, develops advanced carbon-based anode materials for electric vehicle batteries. Led by CEO Rutger van Raalten and CTO Daniela Sordi, the Dutch company addresses supply chain challenges with innovative manufacturing processes to support sustainable battery production.

Battery Technology

CarbonX’s proprietary emulsion feedstock technology produces structured carbon materials for battery anodes with a 3D porous network, enhancing electron and lithium-ion transfer for improved performance and faster charging. The process integrates into existing carbon black facilities to enable localized supply chains, reduces energy consumption and CO2 emissions, matches Chinese graphite cost-effectiveness, and offers high compressibility for increased energy density.

Products

Structured carbon-based anode materials featuring a 3D porous network for enhanced electron and lithium-ion transfer, improved battery performance, faster charging, high compressibility, and seamless integration into existing carbon black production lines.

Recent Projects

In 2024, CarbonX secured €4 million to expand operations, is building a high-capacity feedstock mixing facility in the Port of Rotterdam, conducting feasibility studies for 20 000-ton annual production lines in Europe and the United States, and is in advanced qualification stages with leading global battery manufacturers, with initial supply agreements expected by 2025.

Investors

CarbonX secured a €4M funding extension co-led by Energy Transition Fund Rotterdam (managed by InnovationQuarter), with additional investment from Innovation Industries and Borski Fund.
