Discovery of a potential solid electrolyte for future all-solid Na-ion batteries

Discovery of a potential solid electrolyte for future all-solid Na-ion batteries

The novel compound Na2-x(CB11H12)x(B12H12)1-x shows a fast ionic Na conductivity of 2 mS cm-1 at room temperature, reaching the superionic regime above 333 K. A low activation energy of 314 meV, in a thermodynamically and electrochemically stable structure, suggest its usage as a potential solid electrolyte in future all-solid Na-ion batteries. The discovery was just…

Ph-D defense Yolanda Sadikin

Yolanda Sadikin, PhD student in our group, successfully defended her thesis (“avec felicitations du jury”) on July 25th 2016, entitled “Novel Solid Electrolytes Based on Borohydrides and Higher Boranes”

Design concepts for metal borohydrides in Acta B

A review was published in Acta Crystallographica Section B describing our approach to metal borohydride materials design and the underlying crystal chemistry. We therein report on strong similarities between the structural chemistry of metal oxides and their complex hydride analogues. This analogy has proven to be a powerful tool when rebuilding prominent structure types whilst…

Na – superionics in Advanced Energy Materials

In a recent issue of Advanced Energy Materials we report on a novel class of solid state electrolytes capable of reaching high Na-ionic conductivities at room temperature (superionic). By inserting the borohydride anion into dodekahydroborate materials we introduce additional structural disorder and open migration pathways sufficiently large to allow high mobility of both Na+ and…

ESRF Highlights 2015 – 2 contributions

Two of our recent publications made the 2015 Highlights of the European Synchrotron Radiation Facility (ESRF). The lucky winners were (1) our investigations on stability and structure-property relationships in metal borohydride perovskites and (2) the discovery of novel class of Na – solid electrolytes synthesized by anionic substitution in higher borane materials, which, in terms…
