Investigating Hydrogen Movement and Lithium-Ion Diffusion in Reactive Hydride Composites for Enhanced Hydrogen Storage Performance using QENS and Impedance Spectroscopy

Abstract: This proposal aims to investigate the relationship between hydrogen movement and lithium-ion (Li+) conductivity, correlating these factors with dehydrogenation kinetics in a complex hydrogen storage material composed of Mg(NH2)2, LiH, and LiBH4. By examining hydrogen movement at different stages of dehydrogenation, the study seeks to deepen the understanding of ion transport mechanisms within these materials. The findings will offer insights into how Li+ conductivity relates to the behavior of mobile species, such as BH4? and NH3, during the dehydrogenation process. Ultimately, this research could enhance hydrogen storage materials by optimizing ion transport properties, which are vital for their efficiency and performance in energy storage applications.
