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.
The first-ever proof-of-concept prototypes that enable the creation of printed subsystems were recently completed using a second-generation transistor technology. This advance will pave the way toward the development of demonstrators with optimized electronic integration for specific applications.
Differential voltage measurement was used to develop models that will enable more detailed characterization of lithium-ion battery aging.
Solar photovoltaic cells made using perovskite material are naturally resistant to electronic radiation, making them a potentially-attractive alternative to the multi-junction cells used in space applications.
Liten Annual Report is now online!
Towards large scale integration of solar technologies in building facades, windows, IoT devices or indoor applications
Researchers investigated whether or not additive manufacturing affects a material’s hydrogen resistance. They designed an experiment to test the theory on parts made from Inconel, a material used for certain parts in the Ariane 6 launcher’s engines.
For the first time ever, diesel fuel has been produced by refining the oil contained in biocrude made using hydrothermal liquefaction of microalgae. The first-ever drops of diesel to be obtained in this way prove that this method for producing biofuel is technically feasible—a major step forward.
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.
Automotive equipment manufacturers recently studied the nanoparticle emissions of different types of brake pads leveraging the know-how at Liten, a CEA Tech institute.
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.
Reducing the thickness of the silicon wafers used to manufacture photovoltaic cells is one of the solutions researchers are investigating to lower production costs—but only if it doesn’t weaken the wafers.
The French National Solar Energy Institute (INES) developed and tested an energy management system coupled with battery-based energy storage. The solution is currently being rolled out at the Sainte Rose wind farm in Guadeloupe.
Parametric design optimization can improve heat-exchanger performance. A tool suitable for use in industrial environments was developed to address the multi-scale and multi-physics aspects of heat-exchanger design.
