Replacement of liquid electrolytes in current commercially successful mobile application batteries with solid-state electrolytes will increase battery lifetime and safety due to the greater electrochemical and thermal stability, and diminished flammability. Metal hydrides based on light hydroborate anions such as borohydride [BH4]- or closo-borane anion [B12H12]2- and with high mobility of alkali metal cations such as Li+ and Na+ will be ideal solid-state electrolytes thanks to super-ionic behaviour, high cation transference number, good thermal stability, high electrochemical stability in reducing but also in oxidizing environment, compatibility with Li and Na electrodes and light weight.Our role in here presented project is to transform our accumulated knowledge of hydroborate salts crystal chemistry into design of novel materials with desired properties making them good candidates for solid-state electrolytes. Our recently established borohydride/oxide analogy will be the source of inspiration.At the end of the project we expect understanding the rules controlling the stability of polymetallic hydroborates, being able to design compounds with predicted super-ionic behaviour, directly applicable as solid electrolytes in all-solid Li- and Na-ion batteries.
