Main Research Activities

Industrial PhD (LRCS – Umicore, November 2020-November 2023) Project: Na-ion batteries are catching a lot of attention as a possible alternative to the Li-ion technology due to the unlimited sodium abundance. Despite impressive improvements of their performances in the last few years, safety issues due to the use of a flammable liquid electrolyte is still a major drawback. This is why Na-based All-Solid-State Batteries (Na-ASSB) could be a promising “next generation” of electrochemical energy storage devices. Recently, a new class of solid-state electrolytes has been proposed for Li-ASSB: the Li-Rich Anti-Perovskites related to the archetype Li₃OCl. Their intrinsic high ionic conductivity, stability against lithium metal coupled to a low temperature synthesis process make them materials of great interest. In this project, we propose the synthesis, structural and ionic conductivity characterizations of new Li and Na Anti-Perovskite materials as solid electrolytes. One of the great interests of Li or Na anti-perovskites is their chemical tunability. Anti-Perovskite phases of general formula X3 +B 2-A - can be easily modified by chemical substitution. Those chemical substitutions are expected to increase their ionic conductivity at room temperature.
