Novel borohydrides as solid state ion conductors for electrochemical energy storage

The interest for BH4-based ionic compounds is mainly due to their high gravimetric hydrogen capacity which makes the compounds suitable for hydrogen storage. Beside that, batteries and fuel cells are more and more developed in terms of capacity and safety; the latter could be improved replacing liquid electrolyte (nowadays mostly used) with solid state electrolytes (SSE).

Novel metal-borohydrides are synthesized by mechanochemical method and characterized in order to study the conduction path for mobile cations and their diffusion properties.
