    Abstract

    The adsorption structures of solvents on the surface of LiCoO2, which is the most widely used cathode material for Li-ion batteries, in contact with nonaqueous electrolyte solutions of carbonate esters have been characterized by insitu sum frequency generation (SFG) spectroscopy. The cyclic carbonate of ethylene carbonate (EC) is preferentially adsorbed on the LiCoO2 surface, in contrast to linear carbonates, such as dimethyl carbonate (DMC).
