Enhanced Li-ion conductivity in LiBH4–ZrO2 nanocomposites and nanoscale Li imaging by energy-filtered transmission electron microscopy†
Abstract
A complementary solid-state nuclear magnetic resonance and transmission electron microscopy (TEM) analysis was performed for LiBH4–ZrO2 nanocomposites. As a result, amorphous LiBH4 films with thicknesses of less than 30 nm were observed covering the ZrO2 particles. Li imaging by energy-filtered TEM is useful for the real-space characterization of nanoscale LiBH4.
