Subotica, Serbia, May 11, 2026 – ElevenEs, a leading European manufacturer of lithium iron phosphate (LFP) batteries, and CarbonX, a Dutch developer of advanced carbon-based anode materials, have agreed to extend their strategic cooperation into 2026. This next phase focuses on moving from initial material validation toward rigorous industrial-scale testing, with the goal of strengthening Europe’s local LFP battery supply chain.
As the continent’s only producer of full-scale LFP Edge cells, ElevenEs provides the manufacturing platform and expertise needed to integrate and evaluate novel materials. At its EdgeLabs R&D facility, the company is incorporating CarbonX’s proprietary anode active material into prismatic LFP blade-type cells and conducting benchmarking tests against global performance, lifespan, and safety standards.
ElevenEs will support CarbonX with specialized industrial services, accelerating the transition of CarbonX’s innovations from laboratory research to market‐ready battery components. Pending the successful achievement of defined technical milestones, the agreement envisions a conditional offtake arrangement for CarbonX materials.
Nemanja Mikać, CEO of ElevenEs, commented, “This extended collaboration underlines ElevenEs’s role as an industrial engine for Europe’s battery ecosystem. Beyond material validation, we deliver manufacturing excellence and R&D support to help European innovators scale promising technologies and build a resilient, energy-independent supply chain.”
Rutger van Raalten, CEO of CarbonX, added, “Our continued work with ElevenEs represents a major step toward a sustainable European battery materials industry. By reinforcing our joint supply chain efforts, we contribute to Europe’s strategic goal of energy independence and accelerate the adoption of low-carbon critical materials.”
