Renewable energy and Energy efficiency
CEA Tech institute Liten is working to improve battery lifespans and performance for stationary and mobile energy storage solutions.
The institute conducts testing in real-world conditions and aging tests to gain a deeper understanding of the mechanisms that underpin battery degradation. The goal is to determine the best management strategy for the type of use. The institute also conducts research to determine reliable battery-health indicators.
Liten researchers are helping develop new generations of batteries, like very-low-cost sodium-ion batteries (sodium is abundantly available) and lithium-sulfur batteries, which offer three times the lifespan of lithium-ion batteries of equivalent mass. Liten researchers have already made great strides toward improving the performance and extending the lifespans of these batteries of the future.
ALL TECHNOLOGY PLATFORMS
CEA-Liten, a CEA Tech institute, recently used an advanced X-ray tomography technique to look deep inside lithium-sulfur batteries to understand the mechanisms that underpin degradation—new knowledge that could help improve battery performance and lengthen lifespans.
The Poudr’Innov powder metallurgy platform is ramping up its strip-casting process for magnetic-phase synthesis, positioning Liten, a CEA Tech institute, as a leading developer of high-performance permanent magnets.
Energy Observer, the world’s first hydrogen-powered boat, features an innovative end-to-end energy architecture that is 100% carbon-free, distributed, and digital. Didier Bouix, who heads the project at Liten, a CEA Tech institute, recently won the Mission Innovation Champions award for his work.
New insights into the mechanisms that underpin the dissolution of the components used in lithium-ion batteries have resulted in the development of an improved recycling method.
A new hybrid polymer electrolyte technology with the capacity to enhance battery safety was developed for Solvay. The company has begun presenting the new technology to battery manufacturers.
How to collaborate with CEA Tech teams ?
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
