Liquid electrolytes are still widely used in lithium batteries, but pose a number of safety problems, such as internal short-circuiting, which can lead to fire or explosion...
The alternative is to develop safer, high-performance solid electrolytes. With this in mind, an innovative concept has been developed at the Léon Brillouin Laboratory in Saclay (CEA-Iramis): one-dimensional (1D) confinement of the electrolytic medium to improve the ionic conductivity of electrolytes.
To pursue this approach, a collaboration was initially set up with CEA-LITEN, later joined by the
SyMMES laboratory (CEA-IRIG, CNRS, UGA, Grenoble INP) and the Institut de Chimie Radicalaire (AMU). This consortium has enabled us to understand the phenomena involved through a multi-technique study.
