Research Abstract

Adsorption behaviors of Li atoms and propylene carbonate (PC) molecules were examined on a rutile titanium dioxide (110)-(1×1) surface. Lithium atoms were concentrated at the steps, while PC molecules were stabilized at the bridging O vacancies. The results indicated the controlling of the nanometer-sized structures on the oxide electrode surfaces is the key to optimize the surface-electrolyte interface composed of electrolyte and solvent molecules.
