Liten is a major European research institute and a driving force behind the development of the sustainable energy technologies of the future. The institute is spearheading the EU’s efforts to limit dependency on fossil fuels and reduce greenhouse gas emissions in three key areas: renewable energy, energy efficiency/storage and development of materials.
Our platforms, sophisticated tools for industry & the scientific/technical infrastructure/expertise to overcome technological hurdles
Liten's research teams work across a vast portfolio of renewable energy technologies. Cutting-edge photovoltaic technologies are developed at INES, the French National centre for solar research and R&D with Hydrogen and Biomass activities being managed from the LITEN's main site in Grenoble, Rhone-Alpes.
“Radically improving energy efficiency will reduce the need for investment in energy infrastructure, cut fuel costs, increase competitiveness, lessen exposure to fuel price volatility, increase energy affordability for low-income households and cut local and global pollutants improving consumer welfare” Source OECD Energy report, 2014

Hydrometallurgical processes: a unique alternative for recovering and recycling critical metals
Liten began researching recycling in 2010, with a focus on finding solutions for the end-of-lifecycle management of lithium-ion batteries used in the transportation industry. Since then, we have run a number of hydrometallurgical process programs to develop solutions that comply with Directive 2006/66/EC, which requires that more than 50% of the material in these batteries be recovered. The scope of our hydrometallurgical process research very rapidly expanded beyond battery recycling, encompassing end-of-lifecycle management issues inherent to the technologies developed at our labs and, in particular, those using critical or high-added-value materials. Today, Liten is known for its capacity to develop specific end-of-lifecycle recycling solutions for a variety of technologies and to find new uses for recycled materials in the technologies developed by Liten labs. All of these activities are part of a broader approach to promote environmentally-friendly design principles and reduce the environmental impact of new technologies at every stage of their lifecycle.Hydrometallurgical processes are used to extract and purify metals. These liquid-phase chemical processes separate the different metals contained in an ore or blend of materials so that the metals can then be recycled. No other method can obtain the high levels of purity (greater than 99%) achieved with hydrometallurgical processes. However, when used for recycling, hydrometallurgical processes are only as good as the methods used to prepare the materials before processing. These include dismantling, grinding, and separation to concentrate the metals of interest in a solid fraction before further separation during the hydrometallurgical process. The result? More metal is recovered at lower financial and environmental cost. The approach can recover 80% of the materials in lithium-ion batteries, for example. Our researchers bring know-how in chemistry, chemical engineering, electrochemistry, materials analysis, and materials science in general to deliver research and development services to:
The processes developed are implemented at Technology Readiness Levels 3 to 5 at the CEA and are ready for industrial scale-up and transfer.
