Abstract
- Complex hydrides have played important roles in energy storage area. Here a complex hydride made of Li <subscript>2</subscript> NH and LiBH <subscript>4</subscript> was synthesized, which has a structure tentatively indexed using an orthorhombic cell with a space group of Pna2 <subscript>1</subscript> and lattice parameters of a=10.121, b=6.997, and c=11.457 Å. The Li <subscript>2</subscript> NH-LiBH <subscript>4</subscript> sample (in a molar ratio of 1:1) shows excellent hydrogenation kinetics, starting to absorb H <subscript>2</subscript> at 310 K, which is more than 100 K lower than that of pristine Li <subscript>2</subscript> NH. Furthermore, the Li <superscript>+</superscript> ion conductivity of the Li <subscript>2</subscript> NH-LiBH <subscript>4</subscript> sample is about 1.0×10 <superscript>-5</superscript> S cm <superscript>-1</superscript> at room temperature, and is higher than that of either Li <subscript>2</subscript> NH or LiBH <subscript>4</subscript> at 373 K. Those unique properties of the Li <subscript>2</subscript> NH-LiBH <subscript>4</subscript> complex render it a promising candidate for hydrogen storage and Li ion conduction.<br /> (© 2018 Wiley-VCH Verlag GmbH & Co.
