Neutron study of dynamics of confined fluids in materials of energy applications

Electrical energy storage technologies are essential for storing and releasing energy from renewable sources to mitigate current energy needs. The physicochemical interactions between the electrolyte molecules and the electrode surface control the electrochemical performances, impacting the energy and power densities of energy-storing devices such as batteries and supercapacitors. Those interactions make the dynamics of the electrolytic fluids at the electrode-electrolyte interface differ significantly from their bulk properties. Quasielastic neutron scattering (QENS) is a powerful technique for measuring diffusivity parameters on the atomic to nanometer lengthscales and picosecond to nanosecond in timescales. Here, we present the basis of neutron scattering techniques and the contribution of QENS to explore the fundamental understanding of the microscopic dynamics of confined fluids in energy materials.
