CarbonX, established in 2014 as a spin-off from Delft University of Technology, specializes in creating advanced materials for electric vehicle (EV) batteries. The Dutch company develops unique carbon-based anode materials that serve as alternatives to traditional graphite, addressing critical supply chain challenges in the battery industry. Under the leadership of CEO Rutger van Raalten and CTO Daniela Sordi, CarbonX has positioned itself as an essential contributor to sustainable battery production through its innovative manufacturing processes and materials technology.
Battery Technology
CarbonX’s core innovation lies in its proprietary emulsion feedstock technology, which produces structured carbon materials for battery anodes. This material features a distinctive 3D porous network structure that enhances both electron and lithium-ion transfer, resulting in improved battery performance and faster charging capabilities. The manufacturing process integrates seamlessly into existing carbon black production facilities, enabling localized supply chains and reducing dependence on Chinese graphite sources.
The technology offers several advantages over traditional graphite solutions. The production method consumes significantly less energy compared to synthetic or natural graphite manufacturing, resulting in reduced CO2 emissions. The material matches the cost-effectiveness of Chinese graphite while delivering superior performance characteristics. Additionally, the carbon structure maintains high compressibility, allowing for increased energy density in battery applications.
Recent Projects
In early 2024, CarbonX secured an additional €4 million in funding to expand its operations. The company is currently establishing a high-capacity feedstock mixing facility in the Port of Rotterdam and conducting feasibility studies for 20,000-ton annual production lines in both Europe and the United States. CarbonX is also in advanced qualification stages with several leading global battery manufacturers, with initial supply agreements expected by mid-2025.
Investors
CarbonX’s growth is supported by several significant investors. The company’s recent €4 million funding extension was co-led by the Energy Transition Fund Rotterdam, managed by InnovationQuarter. Other major investors include Innovation Industries, a Dutch deep-tech venture capital firm, and Borski Fund, which focuses on sustainable technology investments. These partnerships have enabled CarbonX to accelerate its technology development and expand its production capabilities.
