TRANS2DCHEM has advanced the state of the art by developing:
a novel nitrogen-doped graphene material (SC-GN3) with unique structural and electrochemical properties;
an industrially compliant, scalable synthesis process for its production; and
application-enabling versatility through SC-GN3’s hydrophilic chemistry and exceptional wettability, contrasting with conventional hydrophobic carbons.
1. SC-GN3 Material Beyond State of the Art
The project introduced SC-GN3, a proprietary nitrogen-doped graphene derivative exhibiting ultra-high energy and power density suitable for next-generation supercapacitors. Its compact architecture ensures high ion accessibility and achieves up to 55 Wh/L, over three times higher than current benchmarks. This advancement enables smaller, lighter, and safer energy storage devices bridging the gap between batteries and capacitors.
Industrial-standard wound-cell prototypes were designed and manufactured, resolving challenges in electrode adhesion, connectivity, and reproducibility. Verified supplier pipelines and standardized assembly protocols ensure long-term production feasibility. Functional prototypes demonstrated excellent cycle life and thermal stability, confirming SC-GN3 as a competitive next-generation carbon electrode combining high volumetric energy density with industrial scalability.
2. Synthesis Process Beyond State of the Art
A scalable, reproducible, and safe industrial synthesis protocol for SC-GN3 has been developed, enabling production in kilogram-scale batches with consistent quality. The process integrates precursor delamination, defluorination, multi-step purification, and controlled drying, with defined QC checkpoints ensuring material reproducibility and compliance with EU safety regulations. Optimized for environmental and operational robustness, the process supports up to 3 kg batches in 100 L reactors, representing a major step from laboratory synthesis and providing transferable know-how for scaling other 2D materials.
3. Application Versatility Beyond State of the Art
SC-GN3’s exceptional conductivity, wettability, and chemical tunability make it suitable not only for supercapacitors but also for biosensing, flexible electronics, and power systems, opening new industrial opportunities. Its hydrophilic surface allows integration into diverse material systems, offering technological adaptability and fostering partnerships through the project’s spin-out company ATOMIVER s.r.o.
These results provide a solid foundation for further upscaling, pilot-line validation, and market deployment. The developed technology demonstrates readiness for industrial adoption and represents a key step toward establishing a European value chain for high-performance carbon-based energy storage materials.
