Understanding Liquid-Liquid Transition Dynamics of Salt Hydrates for Next-Generation Thermal Energy Storage

Abstract: We propose using the OSIRIS spectrometer to perform neutron scattering experiments across newly discovered liquid-liquid transitions in salt hydrates. Selectively deuterated anions will enhance signals from water molecules, which are thought to be the cause of local structure in other LLT systems. Elastic fixed window scans will confirm the presence and temperatures of LLTs, and quasielastic neutron scattering measurements will help us probe rotational and translational dynamics, which are important because LLTs are thought to be caused by a breakdown in rotational dynamics, but not translational dynamics. Insights from these experiments will help us link dynamic processes to ion properties so that we can re-design salt hydrates with high latent heat LLTs. These new systems will be superior thermal energy storage media that will help future generations store and transport heat to cope with intermittent renewable energy supplies.
