GRAPHERGIA builds upon a robust scientific foundation to address challenges in advanced energy materials, device integration, and sustainable manufacturing. The project’s central objective is to develop a science-driven, holistic framework for the one-step, laser-assisted synthesis, processing, functionalization, and direct integration of graphene-based materials and nanohybrids into energy harvesting and storage devices. Combining state-of-the-art advances in laser–material interactions, 2D materials engineering, and scalable deposition methods, the project targets cost-effective, climate-neutral production pathways aligned with EU sustainability goals.
Key advancements beyond the current state-of-the-art include:
•Development of a laser-assisted method for depositing highly conductive graphene through GO reduction on commercial and technical textiles. The method ensures strong adhesion to fibers and has reached large-scale implementation, preparing for roll-to-roll pilot-line integration and significantly advancing textile functionalization technologies.
•Establishment of a novel, single-step laser process to synthesize porous graphene/Si nanohybrids from SiC nanopowders. This binder-free approach, operating under ambient conditions, represents a paradigm shift in LIB anode technology, optimizing both conductivity and silicon activity.
•Design and electrochemical optimization of micro-flexible supercapacitors integrated onto textiles using laser-written graphene. Extensive testing is ongoing, supported by the development of next-generation ionic liquid electrolytes with wide voltage windows to enhance performance.
•Optimization of energy-harvesting fluoropolymer films deposited on graphene-coated textiles via PE-CVD, achieving excellent adhesion, long-term durability, and sustained air permeability, which are key features for scalable and reliable e-textile development.
•Performance tuning of TENG power conditioning circuits, maximizing energy conversion efficiency and compatibility with wearable applications.
•Development of a fully automated test bench, ensuring precise, repeatable characterization and performance validation across multiple device types.
Together, these innovations position GRAPHERGIA at the forefront of sustainable, scalable, and high-performance materials and systems for wearable and battery-based energy technologies.
