2BoSS Project Presentation
Toward Sustainable Batteries Based on Silicon, Sulfur, and Biomass-Derived Carbon
Overview
The European Union is strongly committed to building a competitive and resilient European battery manufacturing value chain to accelerate the transition toward e-mobility. As electric vehicle (EV) adoption continues to rise at unprecedented speed, the need for high-performance, low-impact, and circular battery technologies becomes increasingly urgent.
Future EV fleets will rely on batteries with a wide range of chemistries. Modern cells contain up to a hundred different materials—many of which depend on critical raw materials (CRMs). Without a sustainable and harmonized design, this diversity will create major obstacles for recycling. High variability in material inputs complicates efficient separation, lowers recovery yields, and pushes recyclers to extract only the most valuable elements. To ensure true sustainability in affordable and clean energy, Europe must shift toward circular battery design and reduced CRM dependency.
Project Vision and Objectives
The 2BoSS project aims to develop an innovative, durable, and more sustainable battery technology based on silicon, sulfur, and biomass-derived carbon. By addressing the limitations of current Li-ion technologies, 2BoSS seeks to:
- Reduce reliance on critical raw materials
- Improve material processing efficiency
- Enhance recyclability and circularity
- Extend battery service life
- Achieve more sustainable production and end-of-life strategies
2BoSS will support the emergence of commercial batteries that are compatible with circular economy principles, ensuring better performance and a more environmentally responsible lifecycle.
Collaboration and Approach
Over the next two years, the project will actively engage with industry stakeholders, academic partners, and innovation communities. By fostering a collaborative knowledge ecosystem, 2BoSS will advance product development, experimentation, and the business uptake needed to reach full-scale manufacturing.
The project is coordinated by Prof. Andreu Cabot from the Functional Nanomaterials group at IREC. It brings together several IREC research teams—Nanoionics and Fuel Cells and Energy Storage, Harvesting and Catalysis—alongside leading European partners:
- CEA (France) PI Prof. Pascale Chenevier
- Politecnico di Torino (Italy) – PI- Prof. Gian Andrea Blengini
- Cleopa GmbH (Germany) – PI Dr. Alessandra Manzini
IREC’s role includes producing biomass-derived carbon for cathodes, fabricating cathode electrodes, and assembling and testing battery prototypes.
