Lithium ion batteries enabled the success of portable electronics and dominate the global battery market. The demand for high energy density batteries will further increase with the market trend towards electric vehicles and grid leveling applications. Further improvements in energy density and reduction in cost are key to enable a large scale deployment of batteries for these applications. At high energy densities and large scale, absolute operational safety becomes a stringent requirement. Batteries using a solid state electrolyte instead of the conventional liquid electrolytes have a great potential to overcome the well-known challenges of traditional lithium ion batteries. However, the development of next-generation solid-state electrolytes with high ionic conductivity nearing the conductivity of liquid electrolytes represents a major scientific challenge. Recent years witnessed promising discoveries of novel solid state ionic conductors. Fast sodium ion conductivity was reported in Na2B12H12, a compound containing large dodecahydroborates. This unexpected discovery revealed a new class of superionic conductors, for which the origin of conductivity is yet to be revealed but opens new possibilities for high conductivity. This project aims at developing novel superionic conductors based on closo-borates M(BnHn) towards the application in high energy density batteries. Consisting entirely of low weight elements, closo-borates are ideal for applications that require high gravimetric energy density. We emphasize especially on sodium and magnesium conduction promising lower cost than lithium and in the case of divalent magnesium also higher energy densities. Nanoconfinement and ion substitution will be explored as means to alter the functional materials properties and to stabilize disordered ion conducting phases at room temperature. The inert matrix providing nanoconfinement additionally supports the mechanical and chemical stability of the electrolyte preventing degradation during electrochemical cycling.The project will address the following scientific questions related to this new class of ionic conductors: (i) their thermodynamic/electrochemical stability; (ii) the origin of the ionic conductivity; (iii) development of synthesis methods for the bulk and nanoconfined state; (iv) tuning their properties by ionic substitution. The consortium unites four internationally renowned research groups consisting of Empa, PSI, the University of Geneva, and the Institute of Nuclear Science of the Polish Academy of Sciences in Cracow providing the unique opportunity for forging strong synergies between the researchers that pioneered the field of borates and experts in battery research through the combination of expertise in electrochemistry, solid state chemistry and synthesis, thermodynamics and kinetic, spectroscopy, transport measurements and theoretical modeling.
