Founded in 2014 by Daniela Sordi and Rutger van Raalten, CarbonX is engineering a novel, locally produced anode material designed to replace graphite in lithium-ion batteries. Its patented 3D porous network improves electron and lithium transport, embeds nano-sized silicon, and ultimately raises energy density for applications such as electric vehicles. By tapping existing carbon black plants, the firm can manufacture at graphite-competitive costs while sharply reducing energy use and emissions, helping Europe and the U.S. build independent battery supply chains. Strategically based near Delft University of Technology in the Netherlands, CarbonX also supports battery cell validation for customers. The company positions its process as a solution to global graphite shortages and European dependence on Asian suppliers. Although no revenue or customer numbers were disclosed, the technology has attracted attention from automotive battery stakeholders. The recent EIC award validates the technology and provides capital to accelerate commercialization and market expansion.
