Construction-industry professionals are constantly on the lookout for ways to make the homes they build more energy efficient, which includes making the best use of resources in the environment to ensure effective heating and cooling.
Liten, a CEA Tech institute, recently produced the first-ever cylindrical lithium-sulfur battery. The prototype’s performance indicates a bright future for the batteries!
The Liten Scientific Report is now online.
The 2015 Liten Annual Report is now online.
Liten, a CEA Tech institute, recently developed two pieces of equipment to model hydride breathing, providing valuable insights that could help make hydrogen storage tanks more reliable.
CEA Tech institute Liten recently dimensioned, selected, and tested the components—including the battery—for a complete train on tires for tunnel construction projects. A prototype of the electric-powered train will be tested with Métalliance this fall.
Liten, a CEA Tech institute, has successfully reduced monolike silicon solar cell performance losses due to light-induced degradation to under 2%.
Improved management of water in proton exchange membrane fuel cells (PEMFCs) could help reduce costs and lengthen lifetimes, both of which are crucial to the fuel cells’ commercial success. Research conducted at Liten, a CEA Tech institute, in conjunction with CNRS/IMFT* and PSI** has unlocked some of the secrets to further progress.
Accelerated aging tests provide valuable information about the damage batteries suffer over time. Researchers at CEA Tech in Grenoble and IRAMIS, the Institute of Matter and Radiation of the CEA’s Physical Science Division in Saclay, recently uncovered new information using a novel test in research conducted with labs LRMO (DEN/DPC), LCP, and ICMMO of the University of Paris Sud.
Lithium battery cells produced by Liten, a CEA Tech institute, have passed a first round of tests on the road to qualification for the upcoming Ariane 6 satellite launch mission.
Recent developments at Liten, a CEA Tech institute, could lay the foundations for PV modules with advanced BIST (built-in self-test) capabilities. Faults will be detected and identified in record time, without bringing PV production to a halt.
Liten, a CEA Tech institute, recently produced a small run of PV modules on its dedicated platform. The project was completed in partnership with Mondragon Assembly. And the modules passed IEC 61215 certification testing without a hitch!
CEA Tech wishes to challenge the existing record for the highest quantity of electricity generated by bicycle power (the current record being held by Emanuel Fernando Valdez Avila in Mexico – 495.4 watt hours). In order to try to beat this record CEA Tech’s LETI and LITEN research institutes will use a turbo trainer fitted with a high performance alternator, based on patented CEA Tech technology, at the heart of which lies an extremely powerful bespoke magnet.
Liten's annual report for 2014 is now available.
Lithium-sulfur batteries are ideal candidates for applications requiring high specific energy, but they do have limitations. Thanks to some clever tricks, researchers at Liten, a CEA Tech institute, have successfully overcome the most serious of them.
The Organic/Hybrid Printed Photovoltaic field is growing and is reaching the production scale where development of large area processes is needed. To this aim, researchers from CEA-Liten, based at INES, France, have developed a flexible organic photovoltaic module manufactured entirely by inkjet printing processes that demonstrates power conversion efficiency above 4% for high value, custom-made, solar devices.
By listening to the sounds emitted by batteries, researchers have been able to improve battery charge cycles, enhance functional safety, and control post-manufacturing quality without altering the batteries.
CEA Liten has validated a hydrogen production system using high-temperature steam electrolysis and offering outstanding performance.
