  • After the success of the European NAIADES project, the European Union funds a new research project on sodium-ion batteries.

    On December 17th, the kick-off meeting of the European NAIMA project was held in Amiens in the Hub of Energy. With 15 partners and coordinated by the young company TIAMAT, a spin-off from the RS2E, this project received 8 million euros from the European Union as part of Horizon 2020 project.

    The aim of NAIMA is is to demonstrate the conception of new generation of high-competitive and safe sodium-ion (Na-ion) cells as one of the most robust and cost-effective alternatives to the current and future lithium-based technologies. Several prototypes of Na-ion batteries will be tested for stationary storage applications (renewable generation, industry and private household).

    NAIMA follows the NAIADES project (2015 to 2018) that permitted the conception of the first Na-ion battery prototypes. NAIAM will last 3 years, from December 2019 to November 2022.

  • The European Union unveiled in December 2019 the projects to be funded by the European Research Council.

    Benjamin Rotenberg, research directors at PHENIX and RS2E member, was awarded European grant after applying for the ERC Consolidator Grant calls. He will be one of the 42 French researchers funded by the ERC. The CNRS, which employs most of the laureates, is still in the top 3 of European research institutes.

    On average, each laureate will receive 2 million euros. The funding is provided for up to five years and mostly covers the employment of researchers and other staff to consolidate the grantees' teams. Benjamin Rotenberg and his team will work on "Making Sense of Electrical Noise by Simulating Electrolyte Solution".

  • A RS2E member was awarded one of the “Guy Ourisson” prize for her work.

    The Cercle Gutenberg awarded one of the 6 “Guy Ourisson” prizes to Camélia Gimbheu, RS2E member and senior researcher at IS2M. This award proves the high quality of her scientific researches.

    Prof. Guy Ourisson, renowned Alsatian chemist and former dean of the Louis Pasteur University of Strasbourg, founded the Cercle Gutenberg in 2005. The association awards prizes to young researchers (under 40 years old) every year. Up to 5000 euros, these awards aim to encourage promising researches in Alsace.

    This year, the prizes were funded by Région Grand Est, Eurométropole de Strasbourg, the Fondation Université de Strasbourg, Université de Haute-Alsace and the Fondation pour la recherche en Chimie. Anonymous sponsors also participated.

    The RS2E congratulates Camélia Ghimbeu for this recognition.

  • Researchers from RS2E/ALISTORE have analysed the main studies on inorganic solid-state electrolytes to get a better understanding of their properties.

    A Franco-British team, LRCS/University of Bath, has published a comprehensive review on inorganic solid-state electrolytes, essential elements for the good performances of the all solid-state batteries.

    The study aims to aggregate current knowledge in three research areas needed to control these electrolytes: Multiscale ion transport, electrochemical and mechanical stabilities and processing methods available. Deeper insights about these topics has been gained through the synergy between experimental and modeling techniques.

    In choosing these areas of interest, the review plans to address to the top three current challenges in research on all solid-state batteries. Firstly, the utilization of metal anodes, which have excellent theoretical performance, is slowed down by the inhomogeneous electrodeposition of alkali metals (Li, Na, etc.) through the solid electrolyte. Secondly, the electrolyte/electrodes interfaces are still unstable and poorly known: Interphases form at these locations and interfere with ionic and electronic conduction. Eventually, the electrochemical degradation and the mechanical deformation of the all solid-state batteries under use diminish the physical contact between the different layers, reducing the performances of the energy storage systems proposed.

    The full article, published the 19th August 2019, is available in the journal Nature Materials.

  • The deputy director of RS2E was awarded for his internationally recognized works.

    Patrice Simon, RS2E deputy director and professor in material science at University Toulouse III – Paul Sabatier obtained the Pierre Süe Grand Prix from the French Chemical Society (SCF).

    This prize awards world-class works that corresponds which are part of the activities of the SCF. The Board of Directors of the SCF, a non-profit organization, recognized for its public utility, whose goal is to promote chemistry, has been giving this award every year since 1974.

    Several prizes already distinguish Patrice Simon: The CNRS silver medal* in 2015 and the Brian Conway Prize of Physical Electrochemistry of the International Society of Electrochemistry in 2018.
