A new type of electrolyte for all‐solid‐state batteries is presented by D. Blanchard, P. E. de Jongh, and team on page 184. Confining LiBH 4 in the nanopores of a SiO 2 scaffold leads to a room temperature conductivity of 0.1 mS cm −1 , three orders of magnitude higher than for crystalline LiBH 4 . Lithium ions (blue spheres) move rapidly through LiBH 4 near pore walls, while the core shows more conventional LiBH 4 behavior, albeit with decreased phase transition temperatures.
