Pascale Chenevier from the CEA and is the principle investigator working with Coretec is on the 2BoSS project you can see form the other posts and links ive given . Hopefuilly in the update we are still waiting on from Coretec about the CEA update we will learn if there is any future with the CEA on these projects.
Project: Toward sustainable batteries based on silicon, sulfur and bio-mass derived carbon\
Acronym 2BoSS (Reference Number: JTC-2021_235)
Project Topic The recycling of raw materials to manufacture new components, hence closing the circular economy loop, is especially critical in a fastgrowing and strategic sector such as energy storage. The sustainable production of batteries requires securing the availability of raw materials, and the use of effective strategies for their recycling. Given the intrinsic limitations of current lithium-ion batteries, a new sustainable battery technology is needed. 2BoSS will develop sustainable batteries compatible with the circular economy by: 1) validating a silicon-sulfur battery technology designed to minimize the use of CRMs, provide optimized performance, and enable the circular use of material resources. 2) validating effective recycling strategies for the separation and reuse of raw materials; 3) assessing the cost, life cycle, and environmental, health and safety impact; and 4) designing high-performance products and their scaled-up manufacturing. 2BoSS will validate a battery technology supported on a cobalt-free Li2S-based cathode and a graphite-free silicon-based anode, using nitrogen-doped carbon cloths obtained from organic waste as current collector. Besides improving performance and minimizing the use of CRMs, a key advantage of the battery technology here proposed is the easier recycling of its raw materials. 2BoSS batteries are designed to use no metal collector and to incorporate no metal additive at the cathode, anode and electrolyte, which will allow a more effective and economical separation of the two key raw materials. 2BoSS will design, validate and define the up-scaling of effective lixiviation strategies to separate and regenerate the battery key elements. Additionally, life cycle assessment and social life cycle assessment will be carried out to better understand environmental and social impacts of the developed technology along the life cycle and to provide valuable feedback to optimize their contribution to a more circular economy.
