Polymorphism and solid solutions of trimethylammonium monocarboranes.

Metal -boranes have recently received significant attention as solid-state electrolytes due to their high thermal and electrochemical stability, and the weak interaction between the cat- and anion, facilitating fast ionic conductivity. Here we report a synthesis method for obtaining a novel mixed -carborane compound, [NH(CH)][(CBH)(CBH)(CBH)]. The crystal structures are investigated for [NH(CH)][CBH] and [NH(CH)][(CBH)(CBH)(CBH)], revealing that the latter forms a solid solution isostructural to [NH(CH)][CBH].

Fast magnesium ion conducting isopropylamine magnesium borohydride enhanced by hydrophobic interactions.

New materials for the next generation of electrochemical energy storage devices such as batteries are of extreme importance. Here we investigate the structure, ionic conductivity and thermal properties of isopropylamine magnesium borohydride based composites with different compositions, Mg(BH)·(CH)CHNH, = 0.5, 0.

Methylamine Lithium Borohydride as Electrolyte for All-Solid-State Batteries.

Fast Li-ion conductivity at room temperature is a major challenge for utilization of all-solid-state Li batteries. Metal borohydrides with neutral ligands are a new emerging class of solid-state ionic conductors, and here we report the discovery of a new mono-methylamine lithium borohydride with very fast Li conductivity at room temperature. LiBH ⋅CH NH crystallizes in the monoclinic space group P2 /c, forming a two-dimensional unique layered structure.
