CEA (French Alternative Energies and Atomic Energy Commission) is a public body established in 1945. CEA is a leader in research, development, and innovation, and is active in four main areas: low-carbon energies, defence and security, information technologies and health technologies. In each of these fields, CEA maintains a cross-disciplinary culture of engineers and researchers, building on the synergies between fundamental and technological research. CEA will be involved in the project through its LITEN institute, which is devoted to the development of innovative technologies for the energy transition. CEA LITEN has 950 staff, an annual budget of 130 million euros, and puts in place every year more than 350 research contracts with industrial partners from a wide range of market segments: energy, transport, aerospace, construction, civil engineering, environmental and IT industries, among others. Intellectual Property forms a major part of CEA LITEN activities, with a portfolio of 1,500 international patents. More than 200 articles are published every year in peer reviewed scientific journals.
On this project, CEA will be involved on: Characterizations XPS and ToF-SIMS combined analysis using GCIB (Gas Cluster Ion Beam), FTIR, gel permeation chromatography (GPC) and elemental analysis (WP2), experimentally investigate the transport of sodium in the electrode materials and across the interfaces (WP3), CEA will build a model at the meso-scale of the composite material and compute the ionic conductivity (WP3), CEA will process a baseline pouch cell and associated testing and forensics (WP4), CEA will process materials into cell using extrusion (WP4). Also, CEA will support the dissemination actions (WP7).
