Institut des Matériaux (UMR CNRS-Université de Nantes 6502) was created in 1988 by the renowned French chemist Jean Rouxel. Drawing together chemists, physicists and materials engineers from the CNRS and the University of Nantes, with over 150 researchers and support staff it now represents one of the largest materials research centres in France. Research projects are diverse, including collaborations with industry, and other national and international research organisations.
At IMN a fundamental understanding of materials science and their properties, from the atomic scale upwards, is developed. This allows the design, characterization and optimization of new materials for a wide range of deeptechs, including next generation solar cells, fuel cells, electric car batteries & supercapacitors, nanotechnology, smart materials, materials for microelectronics, photonic and optical materials.
The Institute draws its strength from a convergence of skills, gathered in five research teams:
- Physics of materials and nanostructures (PMN)
- Plasma processes and thin films (PCM)
- Electrochemical storage and conversion of energy (ST2E)
- Innovative materials for optics, photovoltaic and storage (MIOPS)
- Material engineering and metallurgy (ID2M)

Logo AIMEThe team "Aggregates, Interfaces and Materials for Energy" (AIME) associates competence in innovative synthesis routes to hierarchical materials with tailored architecture and in surface reactivity and the chemistry of interfaces, with complementary theoretical and experimental approaches applied to energy storage and conversion and environmental remediation processes.
The perspectives of the research are two-fold: elaboration of original materials enabling emerging energy technologies and the study of the interfacial properties and mechanisms governing exchange of energy and matter at interfaces.

LRCSThe general direction of the Laboratoire de Réactivité et Chimie des Solides is to study the materials from their development to their industrial application, via a thorough characterization. Special expertise of the laboratory concerns materials for electrochemical and electrochromic systems. The coupling of expertise in synthetic chemistry and electrochemistry can offer new solutions to improve different types of batteries (alkaline, lithium and lead). The LRCS is a team of researchers dedicated to the study of the structure/properties of materials, especially in the field of electrochemistry.
To establish such correlations, the team has many characterization equipments (X-ray diffraction, electron microscopy and spectroscopy) that can accurately characterize the materials in general with special expertise in solids in their powder form. The LRCS has a long experience in the field of technical development of materials in aqueous and organic media (green chemistry). A method of preparing metal powders by treatment in an organic phase of polyol has been developed, notably in collaboration with Paris VII. Pure metals or alloys having controlled sizes and shapes of crystal  can be tailor-made by modulating the parameters for the synthesis (type of polyol, temperature, additives). Finally we are very committed to enhance teamwork, which results in sharing our units at national and European levels with the creation, in 2000, of a CNRS prototype unit and in 2004, Alistore Network of Excellence bringing together 17 countries that we coordinate.

RS2EOn July 2nd, 2010 the Ministry of Higher Education and Research created the first National network for Research and Technology on the Electrochemical Storage of Energy.  This network combines research of excellence and innovation through the CNRS with experimental and performing technological centers (CEA, IFP, and INERIS); both of them in close relation with the industrials. RS2E is an integrated research structure composed of various additional organizations:  developing research (academic players), prototyping (institutions for finalized scientific and technological research) and pre-industrialization (creation of a French industrials club) which visionary scientific program tries to solve today’s problems of energy supply while handling and anticipating tomorrow’s needs.
