Periodic Reporting for period 2 - TRANS2DCHEM (Transition of 2D-chemistry based supercapacitor electrode material from proof of concept to applications)
Período documentado: 2023-09-01 hasta 2025-08-31
TRANS2DCHEM addresses the urgent need for high-performance, sustainable energy storage to support Europe’s clean energy transition. Current technologies, such as lithium-ion batteries, face limitations including resource dependency, safety risks, and limited lifetime. Supercapacitors offer a complementary solution with rapid charge/discharge, high power density, and long cycle life, but are limited by energy density and industrial scalability.
The project develops industrially compatible supercapacitors with SC-GN3 electrodes, upscaling electrode material synthesis, optimising additives, slurries, electrolytes, and assembly of both pouch and wound cells. All processes comply with EU standards (RoHS, REACH), ensuring environmental safety and scalability. The project also integrates gender balance and inclusive design, promoting equal participation and accessibility. By combining material innovation, device engineering, and commercialisation pathways, TRANS2DCHEM contributes to EU strategic autonomy in energy storage, fosters sustainable technology adoption, and strengthens Europe’s competitiveness in advanced energy materials.

TRANS2DCHEM achieved substantial progress in the industrial development and validation of the SC-GN3 electrode material and related supercapacitor technologies. A fully industrially compliant synthesis protocol for SC-GN3 was established, optimized, and tested under real industrial conditions in collaboration with COC, enabling batch production of up to 3 kg with strict adherence to industrial standards. In parallel, electrode slurry formulations and electrolyte systems were optimized for scalability and long-term stability, while functional prototypes of pouch and namely wound supercapacitors were successfully assembled and tested by an external laboratory. Wound cell assembly protocols were developed and validated at Itelcond ensuring compatibility with existing industrial manufacturing lines and confirming the feasibility of direct technology transfer. In addition, Life Cycle Assessment (LCA) studies have been achieved. Overall, all technical objectives and deliverables were achieved on schedule, establishing a robust, scalable, and environmentally responsible production framework that bridges the gap between laboratory-scale innovation and industrial manufacturing readiness for SC-GN3-based supercapacitors.
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.
A detailed description of all results is provided in Part B of the Technical Report.
