Imagine a material that's one atom thick, stronger than steel, and conducts electricity better than copper — that's graphene. Europe's biggest research initiative spent over three years turning this wonder material into things you can actually use: batteries that store way more energy, car body panels that are lighter and tougher, brain sensors for medical devices, and even smart textiles. A massive team of 200 organizations across 21 countries built working prototypes and demonstrators, moving graphene from the lab bench closer to the factory floor.

The business problem

What needed solving

Current battery technologies are hitting energy density ceilings, lightweight composites are expensive and hard to optimize, and next-generation neural interfaces need better electrode materials. Companies in energy storage, automotive, and medical devices need advanced materials that deliver step-change performance improvements — but accessing cutting-edge graphene research scattered across hundreds of European labs is nearly impossible without insider knowledge.

The solution

What was built

The project produced 13 demonstration-level deliverables and 121 total deliverables. Concrete outputs include Li-S battery cells targeting 600 Wh/kg, solid-state coin cells with Si-graphene anodes exceeding 800 Wh/L, microsupercapacitors at 100 µm scale, a graphene-enhanced CFRP car body prototype, ECoG neural sensor arrays ready for clinical trials, smart textile prototypes with integrated graphene circuits, and commercial-grade amplifier electronics for graphene brain sensors.

Business applications

Who can put this to work

Battery and energy storage
mid-size
Target: Battery cell manufacturers and energy storage system integrators

If you are a battery manufacturer struggling to push energy density beyond current lithium-ion limits — this project built prototype Li-S cells targeting 600 Wh/kg and solid-state coin cells with Si-graphene anodes reaching over 800 Wh/L with 80% capacity retention after 100 cycles. These graphene-enhanced electrode designs could give you a concrete path to next-generation cells without redesigning your entire production line.

Automotive and aerospace composites
enterprise
Target: Tier 1 automotive suppliers and composite manufacturers

If you are an automotive supplier looking to reduce vehicle weight without sacrificing structural integrity — this project delivered a prototype of graphene-enhanced carbon fiber reinforced polymer (CFRP) car body panels. With 97 industry partners already involved, the manufacturing knowledge is available to help you integrate graphene into existing composite layup processes.

Medical devices and neurotechnology
mid-size
Target: Neural interface and neuroscience equipment companies

If you are a medical device company developing brain-computer interfaces or neurological monitoring tools — this project built an ECoG microelectrode array prototype ready for clinical trials, plus commercial-grade amplifier electronics designed specifically for graphene-based neural sensors. These are not lab curiosities; they were designed for the preclinical and clinical market from the start.

Frequently asked

Quick answers

What would it cost to license or access these graphene technologies?

The project does not publish licensing fees. However, with 97 industry partners and 38 SMEs already in the consortium, multiple commercial pathways likely exist. SciTransfer can identify the right partner and help negotiate access terms for your specific application.

Can these graphene solutions work at industrial production scale?

Several deliverables target industrial relevance — coin and pouch cell battery demonstrators, a CFRP car body prototype, and electronic equipment designed for commercial exploitation. The project explicitly allocated about 30% of its budget to market-motivated spearhead projects, signaling serious scale-up intent.

Who owns the intellectual property from this project?

IP is distributed across 200 consortium partners in 21 countries. Each deliverable typically belongs to the partner who developed it, governed by the consortium agreement. SciTransfer can help you identify which partner holds the IP relevant to your application and facilitate licensing discussions.

How mature are these technologies — are they ready to deploy?

Most outputs are at the demonstrator or functional prototype stage. For example, the Si-graphene battery anode achieved over 800 Wh/L in a coin cell format, and the neural sensor array is cleared for clinical trial use. These are past basic research but still need engineering for full production.

How difficult is it to integrate graphene into existing manufacturing processes?

The project specifically addressed integration challenges across electronics, composites, textiles, and batteries. Deliverables include functional prototypes with stitched and sewn electronic modules and CVD-grown materials for circuit fabrication, suggesting compatibility with established manufacturing methods was a design priority.

Are there regulatory considerations for graphene-based products?

Based on available project data, the ECoG microelectrode array was developed specifically for clinical trials, meaning regulatory pathways were considered from the design phase. For industrial applications like composites and batteries, standard materials certification would apply. Specific regulatory documentation is not detailed in the deliverable descriptions.

What kind of technical support is available post-project?

The project ended in September 2023, but the Graphene Flagship ecosystem continues. With 200 partners including 66 universities and 34 research organizations, deep expertise remains accessible. SciTransfer can connect you with the specific research team behind the technology you need.

Consortium

Who built it

This is one of Europe's largest research consortia with 200 partners across 21 countries — a genuine industrial-scale effort. The 48% industry ratio (97 companies including 38 SMEs) is unusually high for a research project and signals real market pull. Sweden's Chalmers University coordinates, but the heavy lifting spans Germany, France, Italy, Spain, the Netherlands, and beyond. For a business looking to access graphene technology, this consortium is essentially a one-stop directory of who in Europe can make, process, or integrate graphene into products — from battery materials to automotive composites to medical sensors.

How to reach the team

The coordinator is Chalmers University of Technology in Sweden. SciTransfer can help you reach the right work package leader for your specific application area.
