Sustainable Nanocellulose-Carbon Hybrid Electrodes for Advanced Flexible Supercapacitors - CARBONEX-S

Project summary

• Rationale/Needs to be addressed
The transition to renewable energy demands efficient, safe, and sustainable energy storage systems. Conventional supercapacitors rely on fossil-based carbons and toxic solvents, creating environmental and recycling challenges.
• Objectives
CARBONEX-S develops flexible, eco-designed supercapacitors built from boron-doped carbon nanowalls, cellulose nanofibrils (CNFs), and bio-based activated carbon, integrated with aqueous or CNF-gel electrolytes and metal-free laser-induced graphene current collectors.
• Potential applications
The resulting devices target flexible electronics, wearables, and renewable-energy storage modules, offering alternatives to conventional systems.
• Impact and potential benefits
By advancing from TRL 2→5, CARBONEX-S will deliver high-performance and recyclable supercapacitors that reduce CO₂ emissions and resource use, strengthening Europe’s leadership in sustainable energy materials.
