Speeding innovation for industry
Article | Energy storage
By effectively “disconnecting” supply from demand, energy storage will play a crucial role in tomorrow’s grids. CEA Tech is developing a variety of technologies—from battery-based and thermal storage to hydrogen systems—to respond to a range of needs, regulatory and budgetary requirements, and environmental concerns. Stationary storage is emerging as a crucial factor in driving the growth of intermittent renewable energy. One of the biggest challenges facing energy storage is finding a viable business model, one that will require lower costs and enable the delivery of additional services.
CEA Tech is also focusing on storage technologies for mobile applications like vehicle batteries and telephones. These technologies include micro fuel cells and micro-batteries.
A new computer-aided design tool will make battery packs safer by measuring the impact of dimensioning changes on the behavior of the battery packs. Specifically, the tool improves the evaluation of thermal runaway risk.
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.
A characterization method using nuclear magnetic resonance (NMR) spectroscopy was developed to observe the formation of metal lithium in the electrodes of lithium-ion elements during operation. The insights gained will be used to extend electrode lifespans.
A battery abuse-testing platform recently set up in cooperation with Serma Technologies will put batteries to the test in extreme conditions in order to assess their behavior. The platform, housed in a dedicated building, recently completed its first tests on battery modules.
Differential voltage measurement was used to develop models that will enable more detailed characterization of lithium-ion battery aging.
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.
