On Enhancement of the Adsorption-Layer Effect at the Metallic Electrode−Liquid Electrolyte Interface in Specular Neutron Reflectometry Experiments
The possibilities for optimizing the substrate/electrode/electrolyte structure are considered in order to obtain the maximum change in the specular-reflection curves obtained in neutron reflectometry experiments at the electrochemical interfaces between a metallic electrode and liquid electrolyte containing Li+ ions during their operation. The characteristic relations between the scattering length densities of the components, for which the reflection curves most fully provide information about the structure of the solid electrolyte interphase layer formed on the electrode surface during the charge–discharge processes, are determined and analyzed.
