Sulfur-based sustainable batteries for a greener future

Battery technology based on silicon, sulfur and biomass derived carbon.

What is 2BoSS all about?


Validation of a silicon-sulfur battery compatible with the circular economy, designed to minimize the use of CRMs, optimize performance and enable a circular use of material resources.


Validation of effective recycling strategies for the separation and reuse of raw materials, avoiding to use metal collector and to incorporate metal additive at the cathode, anode and electrolyte.


Assessment of the cost, life cycle, and environmental, health and safety impact; and design of high performance products and their scaled-up manufacturing.                                                                                                                                                             

The consortium

This is our team of international experts from Spain, Italy, France and Germany.

Cleopa GmbH

SME provider of innovations in the energy sector with more than 20 years of practical experience.

Commissariat à l'énergie atomique et aux énergies alternatives

Key player in research, development and innovation with a focus on technology for energy, information and health.

Politecnico di Torino

Institut de Recerca en Energia de Catalunya

Research institute working on the development of technologies to enable companies to implement immediate innovative solutions.

Sulfur-based batteries have up to a 90% lower environmental impact than LIBs.

2BoSS proposes bringing LSB technology, optimized in terms of performance, materials used and recyclability, closer to the market.

2BoSS batteries are toxicologically harmless, inexpensive, and based on highly abundant sulfur as an active materials and waste-derived nitrogen-doped carbon as the current collector.
