  • Solar Impulse, a groundbreaking experimental plane who is running thanks to rechargeable batteries and 17 000 photovoltaïc cells just landed in California after a flight over the Pacific. A huge success after a 10-months stay in Hawai because its batteries were seriously damaged due to overheating.

    Talking about the feat, the Russian pilot André Borschberg said : «in 10 years, electric planes will be able to carry fifty people ». A dream shared by the RS2E team but that will only become reality through cutting-edge, worlwide and realistic researches in the energy storage field.

  • Apple wants to boast of significantly longer battery life in its electronic devices. That's why the compagny is currently researching new types of batteries. In order to stay innovative, Apple focuses on new technologies in anodes, cathodes and electrolytes. It seems like ceramic has been choosen to be the electrolyte, because of its fast charging abilities and its improved safatey.

    During the last two months, the american compagny has posted jobs ads to hire scientists specialized in battery development. Those announcements are mainly targeting materials scientists or electrolytes specialists. Those jobs are about evaluating and testing new materials beyond current lithium-ion batteries. But some of them are focused on taking the new batteries from the lab to commercialization.

    All the clues are pointing toward Apple developing a solid-state battery, for which it already has a patent.

  • As part of his work on supercapacitators, Christophe Lethien (from the IEMN lab, a member of RS2E) was interviewed by the RTBF (Belgian TV). The interview follows a publication in Science, with Patrice Simon's group (from the CIRIMAT lab). Supercapacitators are an energy storage device complementary to batteries, e.g. in the case of electric vehicles. The video is available here.


  • With three awards during his 3-years PhD, Matteo Bianchini embodies a new generation of excellence in the field of energy storage. A few days before his PhD defense (23rd October), he has received the Student of the Year Award from the Electrochemical Society!

    The award distinguishes his work at the Laue Langevin Institute in Grenoble (E. Suard) in collaboration with ICMCB* in Bordeaux (L. Croguennec) and LRCS* in Amiens (C. Masquelier and JB Leriche). His researches include the study of the structural mechanisms of insertion/extraction of Li+ in battery materials, using neutron diffraction: a world premiere. He has also been awarded in 2014 the Silver Medal of the Materials Research Society and the "PANalytical Award 2014".

    * ICMCB and LRCS are founding laboratories and heavily involved in RS2E since its inception. Matteo's work is a perfect example of the collaborations happening within network.

    The lab of Jean-Marie Tarascon, director of RS2E, is part of a brand new 6000m2 space at Collège de France (Paris). This scientific center will be inaugurated today by the President of France.

    After a complete renovation of the premises, six chairs are currently present in the new chemistry and physics labs as well as an incubator for young teams. This project shows the ambition of Collège de France in terms of interdisciplinary research in these fields. There are great chances of breakthroughs given the hosted teams world-class level and the place's attractiveness.

    The labs also benefit from the pacified research philosophy at Collège de France, “ a free basic research, without short term application imperatives”, underlines Serge Haroche, the institution's administrator and professor at the quantum physics chair.

    During his visit in Jean-Marie Tarascon's lab, the President will meet the entire team. He will also attend to coin cell making, a widely used format in fundamental and applied research.
